Genes affected

AGTRAP (HGNC:13539): (angiotensin II receptor associated protein) This gene encodes a transmembrane protein localized to the plasma membrane and perinuclear vesicular structures. The gene product interacts with the angiotensin II type I receptor and negatively regulates angiotensin II signaling. Alternative splicing of this gene generates multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.230C>T (p.P77L) alteration is located in exon 4 (coding exon 4) of the AGTRAP gene. This alteration results from a C to T substitution at nucleotide position 230, causing the proline (P) at amino acid position 77 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
