Ambry Genetics RCV000617639 SCV000736453 uncertain significance Cardiovascular phenotype 2024-02-27 criteria provided, single submitter clinical testing The p.C270Y variant (also known as c.809G>A), located in coding exon 2 of the NKX2-5 gene, results from a G to A substitution at nucleotide position 809. The cysteine at codon 270 is replaced by tyrosine, an amino acid with highly dissimilar properties. This variant has been reported in individuals with a variety of phenotypes, including congenital heart defects, Jervell Lange-Nielsen, and dilated cardiomyopathy, as well as in unaffected family members; some cases also had additional cardiac variants detected (Rauch R et al. J. Med. Genet., 2010 May;47:321-31; Abou Hassan OK et al. Sci Rep, 2015 Mar;5:8848; Uysal F et al. BMC Med. Genet., 2017 10;18:114; Monaco I et al. J Electrocardiol, 2018 Dec;53:40-43). This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
