Collection Method: clinical testing

The c.458A>G (p.Y153C) alteration is located in exon 5 (coding exon 2) of the COLCA2 gene. This alteration results from a A to G substitution at nucleotide position 458, causing the tyrosine (Y) at amino acid position 153 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
