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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 07, 2023The c.1619C>T (p.A540V) alteration is located in exon 15 (coding exon 14) of the CHFR gene. This alteration results from a C to T substitution at nucleotide position 1619, causing the alanine (A) at amino acid position 540 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
