Genes affected

PIP (HGNC:8993): (prolactin induced protein) Enables IgG binding activity; aspartic-type endopeptidase activity; and identical protein binding activity. Involved in several processes, including detection of chemical stimulus involved in sensory perception of bitter taste; negative regulation of T cell apoptotic process; and proteolysis. Located in extracellular space and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.193T>C (p.C65R) alteration is located in exon 2 (coding exon 2) of the PIP gene. This alteration results from a T to C substitution at nucleotide position 193, causing the cysteine (C) 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. -
