Genes affected

MAPRE3 (HGNC:6892): (microtubule associated protein RP/EB family member 3) The protein encoded by this gene is a member of the RP/EB family of genes. The protein localizes to the cytoplasmic microtubule network and binds APCL, a homolog of the adenomatous polyposis coli tumor suppressor gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.46).
• BS1: Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0014 (213/152352) while in subpopulation EAS AF= 0.0388 (201/5174). AF 95% confidence interval is 0.0345. There are 6 homozygotes in gnomad4. There are 115 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 213 AD gene.
