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]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.18313548).

Collection Method: clinical testing

The c.297C>G (p.D99E) alteration is located in exon 1 (coding exon 1) of the NKX2-3 gene. This alteration results from a C to G substitution at nucleotide position 297, causing the aspartic acid (D) at amino acid position 99 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
