Post-mortem diagnosis of Pompe disease by exome sequencing in a Moroccan family: a case report
PMID: 30371346
Gene: GAA
They were the parents of a baby girl (V.4) diagnosed at 7 months of life as having isolated severe concentric hypertrophy without outflow obstruction and an ejection fraction of 70%
Case#: V.4, female, age of diagnosis 7 months, Moroccan
DiseaseAssertion: Pompe disease
FamilyInfo: Pedigree (figure 2). V.4 parents are cousins (IV.2 and IV.3). V.4 had a cousin (V.3) that died at 8 months of age and was diagnosed with HCM. V.3 parents (IV.1 and IV.4) are cousins. IV.2, IV.3, IV.1 and IV.4 were all heterozygous for the GAA mutation c.236_246del (p.Pro79ArgfsX13). V.4 was homozygous for the mutation.

CaseNotHPOFreeText: hypotonia without facial dysmorphia or other associated abnormalities.
The heart was structurally normal and no valvular anomalies were observed.
CasePreviousTesting: whole exome sequencing (WES), Sanger sequencing. No metabolic screening was performed.
Molecular analysis of SMN gene excluded Spinal muscular atrophy, one of the major causes of neonatal hypotonia in Morocco.

Exonic sequences were enriched and sequenced with data analysis being used to filter according to inheritance and low allele frequencies in controls. This narrowed down to eight different genes (ADAMTS10, AIRE, C8orf38, DHTKD1, OVOS2, CAMTA2, LPPR3, and RADIL) of which three had been associated with unrelated phenotypes and only one other had predicted pathogenic variants, DHTKD1.

To confirm if a deletion was responsible, copy number analysis by qPRC was performed with Exon 15 showing a dramatic decrease in signal compared to the others in the affected individual suggesting a homozygous deletion. The parents showed a 50% reduction suggesting a heterozygous phase for the deletion. Different primer combinations allowed for confirmation of the breakpoints with a microdeletion of exon 15 and flanking intronic sequence (1522 bp) with a guanosine insertion.

Indeed, in contrast to fibroblasts bearing the I382M mutation, which displayed mild mitochondrial network fragmentation, fibroblasts with the p.R445H and p.S545R mutations were marked by the disappearance of filamentous mitochondria in favour of fragmented and punctuated mitochondria (patients 1–3) (Fig. (Fig.2B2B and Fig. S1). Quantification of the ratio of mitochondrial to cellular volume showed a 20% decrease of mitochondrial content in fibroblasts with the dominant‐negative p.R445H and p.S545R mutations (patients 1–3), compared to control fibroblasts, whereas no significant loss of mitochondrial volume was observed in the haploinsufficient OPA1 mutated fibroblasts (patients 4–7) (Fig. (Fig.2C).2C).
Cultured patient fibroblasts showed disappearance of filamentous mitochondria in favor of fragmented and punctuated mitochondria and a 20% decrease of mitochondrial content in fibroblasts.

CaseAddInfo: Typical variant, Paternity/maternity was confirmed, cDNA analysis confirmed that Variant 1 results in a splice-site donor mutation which skips exon 24 which was confirmed by Sanger sequencing and leads to this deletion: p.His738_Asp770del (c.2212_2310del)

CaseGenotypingMethod: A research panel with 751 genes relating to neurological disorders, including the coding and intronic flanking regions of ACTA1, CFL2, KBTBD13, NEB, TNNT1, TNNT3, TPM2 and TPM3, was used to locate any variants in the proband. These variants were then prioritized and confirmed by Sanger sequencing in the probands and their relatives.

Mutation detection
This paper was listed under the ClinVar entry for this variant; however, only as an example to prove loss-of-function variants in IDUA are known to be pathogenic
In 30 families, either one or both of the mutations were not identified, which accounted for 25.9% of the total alleles. Therefore, all 14 exons of the alpha-L-iduronidase gene were screened in these patients and 23 different sequence changes were found, 17 of which were previously unknown. The novel sequence changes include 4 deletions (153delC, 628del5, 740delC, 747delG), 5 nonsense mutations (Q60X, Y167X, Q400X, R619X, R628X), 6 missense mutations (C205Y, G208V, H240R, A319V, P496R, S633L), a splice site mutation (IVS12+5g>a), and a rare polymorphism (A591T).

ParentalGenotype: Figure 1 has parental genotype information for this proband. It is stated that there is a "hereozygous presence" of an IDUA variant in DNA of patient IV's mother. It is suggested that patient IV inherited a pathogenic variant from his mother. The father of patient IV "carries a benign single nucleotide variant rs115929690 suggesting that patient IV has inherited... a benign variant from his father"
PreviouslyPublished: I do not believe this proband was previously published. The paper states that variant "c.1469T>C have been found in patients previously."
