Genes affected

HTATIP2 (HGNC:16637): (HIV-1 Tat interactive protein 2) Enables protein serine/threonine kinase activity. Involved in import into nucleus and regulation of angiogenesis. Acts upstream of or within positive regulation of programmed cell death; positive regulation of transcription by RNA polymerase II; and protein autophosphorylation. Located in cytosol and nuclear envelope. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.193G>C (p.G65R) alteration is located in exon 2 (coding exon 2) of the HTATIP2 gene. This alteration results from a G to C substitution at nucleotide position 193, causing the glycine (G) at amino acid position 65 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
