Ambry Genetics

Nov 30, 2021

The c.2275C>A (p.L759I) alteration is located in exon 18 (coding exon 17) of the SLC9C2 gene. This alteration results from a C to A substitution at nucleotide position 2275, causing the leucine (L) at amino acid position 759 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
