Description

The p.K1557N variant (also known as c.4671G>T), located in coding exon 32 of the MYH7 gene, results from a G to T substitution at nucleotide position 4671. The lysine at codon 1557 is replaced by asparagine, an amino acid with similar properties. 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.
