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]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: Multiple lines of computational evidence support a deleterious effect 11: AlphaMissense, BayesDel_addAF, BayesDel_noAF, Cadd, Eigen, M_CAP, MutationAssessor, phyloP100way_vertebrate, PrimateAI, PROVEAN, REVEL [when FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]
• BP4: Computational evidence support a benign effect (MetaRNN=0.38331097).
• BP6: Variant 5-127396771-G-A is Benign according to our data. Variant chr5-127396771-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 472745.Status of the report is criteria_provided_single_submitter, 1 stars.
