Genes affected

MEGF10 (HGNC:29634): (multiple EGF like domains 10) This gene encodes a member of the multiple epidermal growth factor-like domains protein family. The encoded protein plays a role in cell adhesion, motility and proliferation, and is a critical mediator of apoptotic cell phagocytosis as well as amyloid-beta peptide uptake in the brain. Expression of this gene may be associated with schizophrenia, and mutations in this gene are a cause of early-onset myopathy, areflexia, respiratory distress, and dysphagia (EMARDD) as well as congenital myopathy with minicores. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Apr 2012]

MEGF10-related myopathy

Pathogenic:2

Pathogenic, criteria provided, single submitter	clinical testing	Invitae	Jan 31, 2024	This sequence change replaces cysteine, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 774 of the MEGF10 protein (p.Cys774Arg). This variant is present in population databases (rs387907072, gnomAD 0.005%). This missense change has been observed in individuals with congenital myopathy (PMID: 22101682, 22371254). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 30965). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. Experimental studies have shown that this missense change affects MEGF10 function (PMID: 23954233, 28498977). For these reasons, this variant has been classified as Pathogenic. -
