Ambry Genetics

Sep 22, 2022

The c.1024G>A (p.V342I) alteration is located in exon 7 (coding exon 6) of the LCLAT1 gene. This alteration results from a G to A substitution at nucleotide position 1024, causing the valine (V) at amino acid position 342 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
