Ambry Genetics

Jan 24, 2024

The c.293G>A (p.R98K) alteration is located in exon 4 (coding exon 2) of the KIAA1456 gene. This alteration results from a G to A substitution at nucleotide position 293, causing the arginine (R) at amino acid position 98 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
