Genes affected
APOBEC3C (HGNC:17353): (apolipoprotein B mRNA editing enzyme catalytic subunit 3C) 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. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 31, 2024The c.234C>G (p.D78E) alteration is located in exon 3 (coding exon 3) of the APOBEC3C gene. This alteration results from a C to G substitution at nucleotide position 234, causing the aspartic acid (D) at amino acid position 78 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
