Genes affected

FOXK2 (HGNC:6036): (forkhead box K2) The protein encoded by this gene contains a fork head DNA binding domain. This protein can bind to the purine-rich motifs of the HIV long terminal repeat (LTR), and to the similar purine-rich motif in the interleukin 2 (IL2) promoter. It may be involved in the regulation of viral and cellular promoter elements. [provided by RefSeq, Jul 2008]

Ambry Genetics

Sep 06, 2022

The c.59C>T (p.A20V) alteration is located in exon 1 (coding exon 1) of the FOXK2 gene. This alteration results from a C to T substitution at nucleotide position 59, causing the alanine (A) at amino acid position 20 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
