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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 15, 2024The c.742G>A (p.A248T) alteration is located in exon 2 (coding exon 2) of the NKX2-3 gene. This alteration results from a G to A substitution at nucleotide position 742, causing the alanine (A) at amino acid position 248 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
