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

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.002521664).
• BS1: Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.0248 (3773/152248) while in subpopulation NFE AF = 0.0397 (2699/68012). AF 95% confidence interval is 0.0384. There are 68 homozygotes in GnomAd4. There are 1767 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High AC in GnomAd4 at 3773 AD gene.
