Genes affected

FHIT (HGNC:3701): (fragile histidine triad diadenosine triphosphatase) The protein encoded by this gene is a P1-P3-bis(5'-adenosyl) triphosphate hydrolase involved in purine metabolism. This gene encompasses the common fragile site FRA3B on chromosome 3, where carcinogen-induced damage can lead to translocations and aberrant transcripts. In fact, aberrant transcripts from this gene have been found in about half of all esophageal, stomach, and colon carcinomas. The encoded protein is also a tumor suppressor, as loss of its activity results in replication stress and DNA damage. [provided by RefSeq, Aug 2017]

The c.242C>G (p.S81C) alteration is located in exon 6 (coding exon 2) of the FHIT gene. This alteration results from a C to G substitution at nucleotide position 242, causing the serine (S) at amino acid position 81 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
