Genes affected

DENND2B (HGNC:11350): (DENN domain containing 2B) This gene was identified by its ability to suppress the tumorigenicity of Hela cells in nude mice. The protein encoded by this gene contains a C-terminal region that shares similarity with the Rab 3 family of small GTP binding proteins. This protein preferentially binds to the SH3 domain of c-Abl kinase, and acts as a regulator of MAPK1/ERK2 kinase, which may contribute to its ability to reduce the tumorigenic phenotype in cells. Three alternatively spliced transcript variants of this gene encoding distinct isoforms are identified. [provided by RefSeq, Jul 2008]

Dec 18, 2023

The c.3284G>A (p.R1095Q) alteration is located in exon 21 (coding exon 17) of the ST5 gene. This alteration results from a G to A substitution at nucleotide position 3284, causing the arginine (R) at amino acid position 1095 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
