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]

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.65A>T (p.Q22L) alteration is located in exon 1 (coding exon 1) of the PIP gene. This alteration results from a A to T substitution at nucleotide position 65, causing the glutamine (Q) at amino acid position 22 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
