Collection Method: clinical testing

The c.1490A>G (p.Y497C) alteration is located in exon 11 (coding exon 11) of the WLS gene. This alteration results from a A to G substitution at nucleotide position 1490, causing the tyrosine (Y) at amino acid position 497 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
