Ambry Genetics

Jun 24, 2022

The c.760G>A (p.V254I) alteration is located in exon 7 (coding exon 7) of the ELOVL2 gene. This alteration results from a G to A substitution at nucleotide position 760, causing the valine (V) at amino acid position 254 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
