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 Benign. Variant got -9 ACMG points.

• BP6: Variant 5-127339115-T-TC is Benign according to our data. Variant chr5-127339115-T-TC is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 350635.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=1, Benign=2}.
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.00102 (156/152234) while in subpopulation EAS AF= 0.0272 (141/5184). AF 95% confidence interval is 0.0235. There are 2 homozygotes in gnomad4. There are 76 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 2 AR gene
