Genes affected

ARGFX (HGNC:30146): (arginine-fifty homeobox) Homeobox genes encode DNA-binding proteins, many of which are thought to be involved in early embryonic development. Homeobox genes encode a DNA-binding domain of 60 to 63 amino acids referred to as the homeodomain. This gene is a member of the ARGFX homeobox gene family. [provided by RefSeq, Jul 2008]

Ambry Genetics

Oct 25, 2022

The c.403A>C (p.K135Q) alteration is located in exon 5 (coding exon 4) of the ARGFX gene. This alteration results from a A to C substitution at nucleotide position 403, causing the lysine (K) at amino acid position 135 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
