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 -21 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.55).
• BP6: Variant 14-73276659-A-G is Benign according to our data. Variant chr14-73276659-A-G is described in ClinVar as [Benign]. Clinvar id is 769401.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=3.12 with no splicing effect.
• BS1: Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.0149 (2269/152168) while in subpopulation AFR AF = 0.039 (1618/41530). AF 95% confidence interval is 0.0374. There are 39 homozygotes in GnomAd4. There are 1083 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
• BS2: High AC in GnomAd4 at 2269 AD gene.
