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]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2023The c.1044G>T (p.E348D) alteration is located in exon 10 (coding exon 8) of the MEGF10 gene. This alteration results from a G to T substitution at nucleotide position 1044, causing the glutamic acid (E) at amino acid position 348 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
MEGF10-related myopathy Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeAug 27, 2021This sequence change replaces glutamic acid with aspartic acid at codon 348 of the MEGF10 protein (p.Glu348Asp). The glutamic acid residue is highly conserved and there is a small physicochemical difference between glutamic acid and aspartic acid. This variant is present in population databases (rs370219469, ExAC 0.009%). 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: 472732). Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The aspartic acid amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
