The c.155A>G (p.Y52C) alteration is located in exon 4 (coding exon 1) of the KIAA1551 gene. This alteration results from a A to G substitution at nucleotide position 155, causing the tyrosine (Y) at amino acid position 52 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
