The c.512C>A (p.S171Y) alteration is located in exon 4 (coding exon 1) of the KIAA1551 gene. This alteration results from a C to A substitution at nucleotide position 512, causing the serine (S) at amino acid position 171 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
