Genes affected

CHFR (HGNC:20455): (checkpoint with forkhead and ring finger domains) This gene encodes an E3 ubiquitin-protein ligase required for the maintenance of the antephase checkpoint that regulates cell cycle entry into mitosis and, therefore, may play a key role in cell cycle progression and tumorigenesis. The encoded protein has an N-terminal forkhead-associated domain, a central RING-finger domain, and a cysteine-rich C-terminal region. Alternatively spliced transcript variants that encode different protein isoforms have been described. [provided by RefSeq, Mar 2014]

Ambry Genetics

May 15, 2024

The c.1385C>T (p.P462L) alteration is located in exon 12 (coding exon 11) of the CHFR gene. This alteration results from a C to T substitution at nucleotide position 1385, causing the proline (P) at amino acid position 462 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
