The c.1469C>A (p.S490Y) alteration is located in exon 12 (coding exon 10) of the CLHC1 gene. This alteration results from a C to A substitution at nucleotide position 1469, causing the serine (S) at amino acid position 490 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
