Genes affected

NUMB (HGNC:8060): (NUMB endocytic adaptor protein) The protein encoded by this gene plays a role in the determination of cell fates during development. The encoded protein, whose degradation is induced in a proteasome-dependent manner by MDM2, is a membrane-bound protein that has been shown to associate with EPS15, LNX1, and NOTCH1. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2016]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.84).
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.00683 (1037/151846) while in subpopulation SAS AF= 0.0297 (143/4816). AF 95% confidence interval is 0.0257. There are 5 homozygotes in gnomad4. There are 565 alleles in male gnomad4 subpopulation. Median coverage is 30. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 1037 AD gene.
