Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PP3_Moderate BS2

The NM_001005743.2(NUMB):​c.875G>A​(p.Arg292His) variant causes a missense change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.00000558 in 1,613,974 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R292C) has been classified as Uncertain significance.

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: Likely_benign. The variant received -2 ACMG points.

• PP3: MetaRNN computational evidence supports a deleterious effect, 0.919
• BS2: High AC in GnomAdExome4 at 8 AD gene.
