| Limb girdle muscular dystrophies, myofibrillar myopathies and distal myopathies v4.24 | ABHD5 |
Oliver Watkinson gene: ABHD5 was added gene: ABHD5 was added to Limb girdle muscular dystrophies, myofibrillar myopathies and distal myopathies. Sources: Literature Mode of inheritance for gene: ABHD5 was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: ABHD5 were set to 33455044 Phenotypes for gene: ABHD5 were set to OMIM 604780 (Chanarin-Dorfman syndrome) Penetrance for gene: ABHD5 were set to Complete Review for gene: ABHD5 was set to GREEN Added comment: Chanarin-Dorfman is a neutral lipid storage disorder. The review here summarises the world literature to date, with a good paragraph about myopathy towards the end of the discussion. The phenotype is quite variable, and can include multiple organ systems, but overall 59% of patients have high CK and muscle weakness. Skeletal muscle biopsy findings of lipid storage in this disorder are well described. Thus, this gene probably ought to be part of R381, and this seems like the best sub-panel to put it in, given that PNPLA2, a similar disorder, is also on this panel. Sources: Literature |

Julia Baptista gene: HMGCR was added gene: HMGCR was added to Limb girdle muscular dystrophies, myofibrillar myopathies and distal myopathies. Sources: Expert Review,Literature Mode of inheritance for gene: HMGCR was set to BIALLELIC, autosomal or pseudoautosomal Publications for gene: HMGCR were set to 37167966; 36745799 Phenotypes for gene: HMGCR were set to Autosomal recessive limb-girdle muscular dystrophy-28; muscle weakness; myopathy Review for gene: HMGCR was set to GREEN Added comment: Several families reported and OMIM entry now available. Morales-Rosado et al. (2023) reported 9 patients from 5 unrelated families with LGMDR28. Symptoms included hypotonia, delayed motor milestones, and axial and neck muscle weakness. Progressive proximal muscle weakness of the upper and lower limbs, waddling gait, muscle atrophy, and increased serum creatine kinase were also described. Biallelic pathogenic variants identified by exome sequencing including missense, in-frame deletion and splice site. Yogev et al (2023) reported 6 affected members of a large consanguineous Bedouin kindred with LGMDR28. In vitro functional studies of the missense variant supported a partial loss of function effect.

| Limb girdle muscular dystrophies, myofibrillar myopathies and distal myopathies v2.47 | MYH7 |
Arina Puzriakova Added comment: Comment on mode of inheritance: Gene has been re-curated and the MOI should be updated from 'monoallelic' only to 'both mono- and biallelic' at the next GMS panel update. Association with monoallelic variants is well-established. There are now at least four families in literature with recessive variants and myopathy (PMIDs: 14659406; 25666907; 17372140; 31130376). Most commonly described is scapuloperoneal and proximal distribution of muscle weakness, which are within the scope of this panel. |

Recurring variant, Asn155ser, identified in multiple families of different ethnicity. Age of onset variable between families. Mostly normal CK levels PMID: 30345904: 1 family reported with Asn155Ser variant. Normal CK level. Progressive muscle weakness began at the age of 9. PMID: 30515627: 3 Finnish families reported, Asn155Ser, reported on at least one allele. Patients presented with LGMD-type phenotype, onset >20. EMG showed myopathic changes. Normal CK levels. PMID: 27745833: 5 families reported (includes 2 consang Turkish families, hom Asn155Ser). Authors concluded gene as causative for early-onset myopathy, normal to moderately elevated CK levels. EMG was myopathic in all individuals tested Sources: Expert list |
