Genes affected

PHB1 (HGNC:8912): (prohibitin 1) This gene is evolutionarily conserved, and its product is proposed to play a role in human cellular senescence and tumor suppression. Antiproliferative activity is reported to be localized to the 3' UTR, which is proposed to function as a trans-acting regulatory RNA. Several pseudogenes of this gene have been identified. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

Ambry Genetics

Jun 05, 2024

The c.277C>T (p.R93C) alteration is located in exon 4 (coding exon 3) of the PHB gene. This alteration results from a C to T substitution at nucleotide position 277, causing the arginine (R) at amino acid position 93 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
