Ambry Genetics

Nov 20, 2023

The c.3736A>C (p.I1246L) alteration is located in exon 15 (coding exon 15) of the KIAA1429 gene. This alteration results from a A to C substitution at nucleotide position 3736, causing the isoleucine (I) at amino acid position 1246 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
