Genes affected

NKX2-5 (HGNC:2488): (NK2 homeobox 5) This gene encodes a homeobox-containing transcription factor. This transcription factor functions in heart formation and development. Mutations in this gene cause atrial septal defect with atrioventricular conduction defect, and also tetralogy of Fallot, which are both heart malformation diseases. Mutations in this gene can also cause congenital hypothyroidism non-goitrous type 5, a non-autoimmune condition. Alternative splicing results in multiple transcript variants.

The S313L variant has not been published as a pathogenic variant, nor has it been reported as a benign variant to ourknowledge. The S313L variant was not observed in approximately 6,500 individuals of European andAfrican American ancestry in the NHLBI Exome Sequencing Project, indicating it is not a commonbenign variant in these populations. The S313L variant is a non-conservative amino acid substitution,which is likely to impact secondary protein structure as these residues differ in polarity, charge, sizeand/or other properties. However, this substitution occurs at a position that is not conserved acrossspecies. Consequently, in silico analysis is inconsistent in its predictions as to whether or not thevariant is damaging to the protein structure/function. Finally, no missense variants in nearby residueshave been reported in the Human Gene Mutation Database in association with NKX2-5-relateddisorders (Stenson et al., 2014), indicating that this region of the gene is not known to harbor disease-causingvariants. -
