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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.261G>C (p.R87S) 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 261, causing the arginine (R) at amino acid position 87 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
