METHODS SUPPLEMENT.
GENETIC TESTING
GLA gene
The seven exons of the GLA gene were amplified from peripheral blood-derived genomic deoxyribonucleic acid by means
of polymerase chain reaction. The polymerase chain reaction fragments were analyzed by means of denaturing highperformance liquid chromatography using the wave deoxyribonucleic acid fragment analysis system (Transgenomic, San
Jose, California). Heteroduplex fragments were purified (QIAquick Kit, Qiagen, Santa Clarita, California) and then
sequenced using a BigDye-terminator cycle sequencing system (ABI PRISM, Applied Biosystems, Foster City, California).
Reference sequence used in the study is ENST00000218516.
Definition of mutations and variants
Criteria for defining genetic variants as pathogenic were:

Nonsynonymous genetic variant, both known and previously demonstrated to cause AFD.

Novel proven to be associated with low a-GAL activity and/or intracellular GB3 accumulation.

Truncation-predicting mutation and in-frame deletions predicting loss of key residues for the function of the
protein.

Mutations predicting the substitution of Cysteine (Cys) residues, both involved in disulfide bonds (52-94; 56-63;
202-223; 378-382) and catalytic sites (142-172) as well as unpaired Cys (90 and 174).

Absence of the variant in a large number of controls (1000 Genomes Project, Exome Variant Server (EVS) and
dbSNP137) or minor allele frequency (MAF) <0.01.

Conservation of the affected amino acid in different species through evolution (conservation score);

Predicted pathogenicity (Polyphen 2, SIFT, Mutation Taster).

Pathologic study of affected tissue/s demonstrating intracellular GB3 accumulation using electron microscopy
and immunohistochemistry.

Segregation studies in families demonstrating that mutation carriers show disease manifestations.


Multigene panels in patients with prominent left ventricular hypertrophy
For the Miseq Illumina we used a custom designed panel with Nextera Rapid Capture Sequencing Kit v2. After library
preparation with Nextera tagmentation method, barcodes were added and sample pulled. Next, libraries were denatured
and biotin-labeled probes specific to the targeted region were used for Hybridization. Biotinylated DNA fragments bound
to the streptavidin-coated beads were magnetically pulled down from the solution. The enriched DNA fragments were
then hybridized and prepared for a second capture. Twelve samples per run were sequenced, according to Illumina
preparation protocols. Sequences were analyzed by mapping all of the generated sequencing reads to the hg19 human
genome reference (UCSC) with dbSNP 138 using GATK(v2.4) for variant calling and Variant Effect Predictor (v85) for
variant annotation and interpretation.

PLASMA AND LEUKOCYTE ASSAY
3
The -Gal A activity was determined in plasma and in leukocytes using the synthetic fluorogenic substrate, 4methylumbelliferil--D-galactopyranoside (Sigma-Aldrich, Steinheim, Germany), according to a previously described
protocol with a few changes 1, in the presence of N-acetyl-D-galactosamine (Sigma-Aldrich, Steinheim, Germany), a
specific inhibitor of galactosidase B.
Briefly, for measuring plasma -Gal A, 50 L of plasma were reacted with 300 L of the substrate solution (3 mmol/L in
0.15 mol/L citrate/phosphate buffer, pH 4.8) and 50 L of the inhibitor N-acetyl-galactosamine (0.8 mol/L). The samples
were incubated in bath water at 37 °C for two hours and the reaction was stopped by adding 3.5 mL of 0.2 mol/L
glycine/carbonate buffer, pH 10.7. The leukocytes samples were obtained by the heparinized blood centrifuged at 3000
rpm at room temperature for 10 minutes, and the remaining blood was used to separate leukocytes following a standard
Ficoll-Paque method; the pellet obtained was diluted in distilled water, sonicated, and analyzed for total protein content
trough the colorimetric technique by Lowry et al 2. In the PBMC assay, 25 L of leukocytes homogenate were incubated
for an hour at 37° C with 100 L of substrate solution (7.5 mmol/L in distilled water) and 25 L of Na-acetate buffer,
1mol/L, pH 4.5. Reaction was stopped with the addition of 2 mL of glycine-carbonate buffer, pH 10.7 and the resulted
fluorescence was determined in a Kontron Spectrofluorometer (Uvikon SFM25), (exc: 360 nm; em: 450 nm). Readings
were corrected for blanks and compared with 4-methylumbelliferone calibrator (10 mmol/L). The results of leukocytes
assay represent specific enzyme activity, since they take in consideration the amount of total proteins in a sample, being
expressed as nmol of substrate degraded per hour per mg of the cell protein (nmol/mg prot/h), while the results for
plasma indicate total enzyme activity, being expressed as nmol of substrate per hour per mL of plasma (nmol/mL/h). For
all types of samples, the activity of a reference enzyme, usuallymannosidase, was measured to assure sample quality.
We generated standards for reference values of plasma and leukocytes Gal A activities in wild-type subjects in
accordance with the Standards for Reporting of Diagnostic Accuracy principle.

PATHOLOGY STUDIES
Tissue biopsies were routinely processed for light and electron microscopy. Light and electron immunochemistry was
performed using anti-Gb3 monoclonal antibody (TCI Chemicals, clone BGR23, formerly sold as Seikagaku cat. #370680)
with DAKOTMEnVision secondary antibody for light microscopy and goat anti-mouse, colloidal gold 15nm (Bb
International) secondary antibody for immuno-electron microscopy.
IN VITRO CELLULAR STUDIES
Blood samples (3 ml) were collected in EDTA-treated tubes and Peripheral Blood Mononuclear Cells (PBMCs) were
isolated by standard density-gradient centrifugation (Histopaque®-1077, Sigma-Aldrich). PBMCs were immediately plated
on cover glass placed in the culture dish with opportune growth medium (Advanced Dulbecco's Modified Eagle
4
Medium ,Gibco, Life Technologies) supplemented with 10% Fetal Bovine Serum, 2mM L-glutamine, 0.1 mg/ml penicillin /
100 U/ml streptomycin and 1x MEM Non-Essential Amino Acids Solution. After 7-10 days of culturing at 37° C in a
humidified 5% CO2 incubator the adherent cells appeared. The cells were fixed and fluorescent staining on this glasses
directly. Nuclei were stained with DAPI solution (Ultracruz Mounting Medium, Santa Cruz).
For the immunofluorescence studies of the Gb3 accumulations, the cells were fixed with 4% paraformaldehyde in PBS 1X
on ice for 15 min and incubated with primary anti-Gb3 antibody (Anti-Gb3 Monoclonal Antibody, clone BGR23, TCI
Chemicals). Anti-mouse Cy3 conjugated (Jackson ImmunoResearch Laboratories) was used as secondary antibody. Nuclei
were stained with DAPI solution (Ultracruz Mounting Medium, Santa Cruz).
For detecting the expression of alpha galactosidase (a-GLA), the cells were fixed with 100% methanol on ice for 10 min
and incubated with primary antibody (Anti-GLA Polyclonal Antibody, Atlas Antibodies). We used anti-rabbit Cy5
conjugated (Jackson ImmunoResearch Laboratories) as secondary fluorescent antibody. All antibodies were diluted in 4%
of Skim Milk Powder (Fluka Analytical) in 1x PBS.
Images were acquired by Nikon D-Eclipse C1 confocal microscopy and EZ-C1 Software.
Statistical analysis
Descriptive statistics were computed as median and IQR for continuous variables. In addition to the main statistical
analysis in the consecutive series of probands (main text), we here used non-parametric statistics for dependent data
(Wilcoxon rank sum test) stratified for family, in case of p.(Asp313Tyr) and p.(Asn215Ser) because they were found in
more families. A p value of <0.05 was considered statistically significant. MEDCALC version 14.10.2 (MedCalc Software,
Belgium) was used for statistical evaluation.
RESULTS SUPPLEMENT.
Organ/system involvement
Of the 37 probands, 12 were the unique family members (including one patient with proven de novo mutation): seven
had family history suggestive for AFD in one non-tested deceased parent; four had no relatives. The 60 mutated relatives
were from 25 families; we traced detailed clinical information for four obligate carriers, which are included in the
evaluation. 5 females accepted genetic testing but refused multidisciplinary clinical controls. Overall, we had clinical
information in 96 mutation carriers: 86 mutated family members were affected including 2 only complaining
acroparesthesias; 10 were healthy carriers. Of the 86 affected family members, 22 (28%) demonstrated the involvement
of one organ (n=14) and 1 organ plus acroparesthesias (n=8), while 62 had involvement of more than one organ (up to 7)
(72%) (Individual data are reported in Table 5 supplement).
GLA activity in patients with [p.(Asp313Tyr)] pseudodeficiency allele
The 8 probands who were carriers of this variant were from the neurology setting. 31 relatives of the 8 probands
underwent genetic screening and enzyme activity testing: overall, 25 family members were carriers and 14 were wild type.
Although numbers are low and non-sufficient for a robust comparative evaluation, we report available data on enzyme
activity, stratified for family members. Plasma for enzyme dosage was available in 10 mutated males from 6 families [2.15
nmol/mL/h (IQR 2-2.7)] and in 7 WT male relatives from 4 families [9.475 nmol/mL/h (IQR 5.46-13.1)] (p<0.001). Plasma
for enzyme dosage was available in 16 mutated females from 7 families [5.55 nmol/mL/h (IQR 2.71-6.7)] and in 6 WT
5
female relatives from 5 families [7.9 nmol/mL/h (IQR 6.475-8.2)] (p=0.033). Leukocytes for enzyme dosage were available
in 8 mutated males from 4 families [17.9 nmol/mgprot/h (IQR 10.525-19.0875)] and in 6 WT male relatives from 3 families
[26.12 nmol/mgprot/h (IQR 23.46-26.76)] (p=0.56). Leukocytes for enzyme dosage were available in 11 mutated females
from 6 families [20.075 nmol/mgprot/h (IQR 15.41-19.35)] and in 5 WT female relatives from 4 families [19.375
nmol/mgprot/h (IQR 11.575-27.2875)] (p=0.92).
GLA activity in patients with [p.(Asn215Ser)]
The 5 probands who were carriers of this mutation came from the cardiology setting. 19 relatives of the 5 probands were
mutation carriers. Although numbers are low and non-sufficient for a robust comparative evaluation, we report available
data on enzyme activity in probands, stratified for family members. Plasma for enzyme dosage was available in 9 mutated
males in 3 families [0.67 nmol/mL/h (IQR 0.42-0.7)] and in 10 mutated females from 3 families [3.32 nmol/mL/h (IQR 34.91)]. Leukocytes for enzyme dosage were available in 7 mutated males from 3 families [3.31 nmol/mgprot/h (IQR 2.874.25)] and in 10 mutated females from 3 families [10.73 nmol/mgprot/h (IQR 8.759-18.32)].

Exome Server DB (last access 21 04 2016) (http://evs.gs.washington.edu/EVS/); ° http://genetics.bwh.harvard.edu/pph2; ^http://sift.jcvi.org. § First manuscript that described the mutation. The mutation segregates in family
members. The probands was also tested for known hypertrophic cardiomyopathy genes, and resulted negative. The activity of the enzyme resulted minor then the cutoff level and the variant was not present in EVS. †This mutation
was associated with late onset phenotype and segregated with the phenotype in the family. ** this patient demonstrated severe phenotype and GB3 accumulation in the gastric biopsy (Figure4).

TABLE 5 SUPPLEMENT. MOGE(S)
The table shows the list of probands and relatives diagnosed with AFD, their position in family pedigrees, and the MOGE(S) descriptor for cardiomyopathies (web-app at
http://moges.biomeris.com/moges.html, app for Android downloadable from Google Play):
M Morphofunctional (M) phenotype of the hypertrophic cardiomyopathy (H) and obstructive (Obs) and non-obstructive (N-Obs) specifications. Overlapping or evolving morphofunctional
profile (i.e. D=Dilated), Early (E) hypertrophic cardiomyopathy (Max LV: 11-14mm), short PR (<PR) interval or Atrio-Ventricular block (AVB) at ECG can be added.
O Organs/systems’ involvement (O):
 heart (H);
 Kidney (K) in case of microalbuminuria, albuminuria, proteinuria; Chronic renal Failure (CRF) renal transplantation (KTx), and dialysis can be further specified;
 Central nervous system (N) either stroke, or transient ischemic attack (TIA), or migraine and imaging markers such as white matter lesions (WML);
 Peripheral nervous system (Acroparesthesia);
 Cutaneous (C) system (e.g. typical angiokeratomas);
 Gastro-enteric system (GE);
 Ocular (E) for Eye describes non-iatrogenic cornea verticillata, E(CV);
 Auditory system (A).
G Genetic (G) or unknown/unproven (U) genetic origin of the disease. In AFD the pattern of inheritance is described as X-linked (XL)
E Etiology (E) in AFD corresponds to mutations in the GLA gene; mutation is in red when pathogenic, yellow in case of genetic variant of unknown significance (GVUS). Green SNP with
some potential functional implication; variants additional to those observed in GLA are added after the GLA mutation.
(S) Stage (S) descriptor includes both the AHA-ACC stage A-D and the NYHA function class (I-IV).

*1 proven affected sister, not included in this list. °4 affected brothers. ^ 2 additional affected sisters of II:3; HC: Healthy Carrier. OC= obligate carrier with available clinical information. Hypertension (HPN). IHD=Ischemic Heart Disease. § Giant
Aneurysm of the left internal carotid artery (Diameter 30mm, partly thrombosed) in the suprasellar segment near the origin of the ophthalmic artery causing compression and displacement of the optic chiasm and left optical nerve in the prechiasmatic
segment. sCPK: serum creatin-phosphokinase PKU = Phenylketonuria. RA: Rheumatoid arthritis. NIDDM: Non-insulin-dependent diabetes mellitus.

FIGURE 1 SUPPLEMENT.
Endomyocardial biopsy from a patient carrier of the p. (Phe113Leu): the maximal left ventricular thickening was
28mm. A) The panel shows areas of interstitial fibrosis with typical Fabry bodies in the interstitial spaces and myocytes
that demonstrate extensive myofibriallar lysis and Fabry bodies. B) Immunoelectron micrograph showing anti-Gb3
specific labeling of the osmiophilic lamellar bodies.

FIGURE 2 SUPPLEMENT.
The figure shows electron (A,B,C,E) and light microscopy (D) views of morphologic (A-C,E) and anti-GB3
immunohistochemistry (D) features of skin biopsies taken from patients carriers of the p.Asp313Tyr. Osmiophilic
lamellar bodies are rare and scattered as confirmed by the spotty immunoreactive bodies seen in the smooth muscle
cells of skin arteriolar vessels (D). Therefore, skin biopsies are not contributory to the understanding of the potential
role of this variant in the phenotype presented by patients.
20
FIGURE 3 SUPPLEMENT.
The figure shows electron micrographs from punch skin biopsies taken to demonstrate the presence of lamellar
bodies in vessels. The samples have been extensively investigated and did not show typical and significant
accumulations of Gb3. D panel shows osmiophilic extracellular material non-sufficient for a morphologic diagnosis.

FIGURE 4 SUPPLEMENT.
Pedigree of one of the families with the p. (Asp313Tyr). All carriers are affected and show more than one trait
recurring in AFD (in blue).
