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]

This sequence change creates a premature translational stop signal (p.Arg1056*) in the MEGF10 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MEGF10 are known to be pathogenic (PMID: 22101682, 22371254, 23453856, 23954233). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with MEGF10-related conditions. ClinVar contains an entry for this variant (Variation ID: 472740). For these reasons, this variant has been classified as Pathogenic.
