Genes affected

BARX2 (HGNC:956): (BARX homeobox 2) This gene encodes a member of the homeobox transcription factor family. A highly related protein in mouse has been shown to influence cellular processes that control cell adhesion and remodeling of the actin cytoskeleton in myoblast fusion and chondrogenesis. The encoded protein may also play a role in cancer progression. [provided by RefSeq, Jul 2008]

Collection Method: clinical testing

The c.424G>A (p.E142K) alteration is located in exon 2 (coding exon 2) of the BARX2 gene. This alteration results from a G to A substitution at nucleotide position 424, causing the glutamic acid (E) at amino acid position 142 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
