Genes affected

DAB2IP (HGNC:17294): (DAB2 interacting protein) DAB2IP is a Ras (MIM 190020) GTPase-activating protein (GAP) that acts as a tumor suppressor. The DAB2IP gene is inactivated by methylation in prostate and breast cancers (Yano et al., 2005 [PubMed 15386433]).[supplied by OMIM, May 2010]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.959

The c.650C>G (p.T217S) alteration is located in exon 6 (coding exon 6) of the DAB2IP gene. This alteration results from a C to G substitution at nucleotide position 650, causing the threonine (T) at amino acid position 217 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
