Ambry Genetics | RCV004026887 | SCV000849671 | uncertain significance | not specified | 2019-06-29 | criteria provided, single submitter | clinical testing | The p.R57W variant (also known as c.169C>T), located in coding exon 3 of the KATNAL2 gene, results from a C to T substitution at nucleotide position 169. The arginine at codon 57 is replaced by tryptophan, an amino acid with dissimilar properties. This amino acid position is not well conserved in available vertebrate species, and tryptophan is the reference amino acid in other 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. |
