The c.413A>T (p.Y138F) alteration is located in exon 2 (coding exon 1) of the KIAA1958 gene. This alteration results from a A to T substitution at nucleotide position 413, causing the tyrosine (Y) at amino acid position 138 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
