Genes affected

VENTX (HGNC:13639): (VENT homeobox) This gene encodes a member of the Vent family of homeodomain proteins. The encoded protein may function as a transcriptional repressor and be involved in mesodermal patterning and hemopoietic stem cell maintenance. Multiple pseudogenes exist for this gene. A transcribed pseudogene located on chromosome X may lead to antigen production in certain melanomas. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage

Oct 03, 2022

The c.440A>G (p.K147R) alteration is located in exon 3 (coding exon 3) of the VENTX gene. This alteration results from a A to G substitution at nucleotide position 440, causing the lysine (K) at amino acid position 147 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
