Genes affected

APOBEC3F (HGNC:17356): (apolipoprotein B mRNA editing enzyme catalytic subunit 3F) This gene is a member of the cytidine deaminase gene family. It is one of seven related genes or pseudogenes found in a cluster, thought to result from gene duplication, on chromosome 22. Members of the cluster encode proteins that are structurally and functionally related to the C to U RNA-editing cytidine deaminase APOBEC1. It is thought that the proteins may be RNA editing enzymes and have roles in growth or cell cycle control. Alternatively spliced transcript variants encoding different isoforms have been identified.

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.7C>A (p.P3T) alteration is located in exon 1 (coding exon 1) of the APOBEC3F gene. This alteration results from a C to A substitution at nucleotide position 7, causing the proline (P) at amino acid position 3 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
