Description

The p.D157Y variant (also known as c.469G>T), located in coding exon 4 of the SDHAF2 gene, results from a G to T substitution at nucleotide position 469. The aspartic acid at codon 157 is replaced by tyrosine, an amino acid with highly dissimilar properties. This amino acid position is well conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this alteration remains unclear.
