Genes affected

PYHIN1 (HGNC:28894): (pyrin and HIN domain family member 1) The protein encoded by this gene belongs to the HIN-200 family of interferon-inducible proteins that share a 200-amino acid signature motif at their C-termini. HIN200 proteins are primarily nuclear and are involved in transcriptional regulation of genes important for cell cycle control, differentiation, and apoptosis. Downregulation of this gene is associated with breast cancer. This protein acts as a tumor suppressor by promoting ubiquitination and subsequent degradation of MDM2, which leads to stabilization of p53/TP53. Alternatively spliced transcript variants encoding different isoforms have been described for this gene. [provided by RefSeq, Aug 2011]

The c.1123T>C (p.F375L) alteration is located in exon 6 (coding exon 5) of the PYHIN1 gene. This alteration results from a T to C substitution at nucleotide position 1123, causing the phenylalanine (F) at amino acid position 375 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
