Genes affected

FAN1 (HGNC:29170): (FANCD2 and FANCI associated nuclease 1) This gene plays a role in DNA interstrand cross-link repair and encodes a protein with 5' flap endonuclease and 5'-3' exonuclease activity. Mutations in this gene cause karyomegalic interstitial nephritis. Alternatively spliced transcript variants encoding distinct isoforms have been described. [provided by RefSeq, Feb 2016]

Ambry Genetics

Sep 16, 2021

The c.296C>T (p.P99L) alteration is located in exon 2 (coding exon 1) of the FAN1 gene. This alteration results from a C to T substitution at nucleotide position 296, causing the proline (P) at amino acid position 99 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
