Ambry Genetics

Nov 12, 2024

The c.350G>C (p.S117T) alteration is located in exon 4 (coding exon 3) of the LCLAT1 gene. This alteration results from a G to C substitution at nucleotide position 350, causing the serine (S) at amino acid position 117 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
