The c.145A>G (p.K49E) alteration is located in exon 1 (coding exon 1) of the KIAA1522 gene. This alteration results from a A to G substitution at nucleotide position 145, causing the lysine (K) at amino acid position 49 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
