Genes affected

MIB2 (HGNC:30577): (MIB E3 ubiquitin protein ligase 2) The protein encoded by this gene is an E3 ubiquitin protein ligase that mediates ubiquitination of proteins in the Notch signaling pathway. The encoded protein may be a suppressor of melanoma invasion. [provided by RefSeq, Mar 2017]

Collection Method: clinical testing

The c.38C>A (p.S13Y) alteration is located in exon 1 (coding exon 1) of the MIB2 gene. This alteration results from a C to A substitution at nucleotide position 38, causing the serine (S) at amino acid position 13 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
