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]

Collection Method:clinical testing

The c.1252G>T (p.G418C) alteration is located in exon 13 (coding exon 10) of the NUMB gene. This alteration results from a G to T substitution at nucleotide position 1252, causing the glycine (G) at amino acid position 418 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
