Ambry Genetics

May 10, 2024

The c.2999G>A (p.R1000H) alteration is located in exon 14 (coding exon 14) of the KIAA1755 gene. This alteration results from a G to A substitution at nucleotide position 2999, causing the arginine (R) at amino acid position 1000 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
