Genes affected

NKX2-3 (HGNC:7836): (NK2 homeobox 3) This gene encodes a homeodomain-containing transcription factor. The encoded protein is a member of the NKX family of homeodomain transcription factors. Studies of similar proteins in mouse and rat have indicated a potential role in cellular differentiation.[provided by RefSeq, Mar 2010]

The c.337G>T (p.V113F) alteration is located in exon 1 (coding exon 1) of the NKX2-3 gene. This alteration results from a G to T substitution at nucleotide position 337, causing the valine (V) at amino acid position 113 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
