Ambry Genetics

Jan 23, 2024

The c.1946G>A (p.S649N) alteration is located in exon 14 (coding exon 14) of the LSG1 gene. This alteration results from a G to A substitution at nucleotide position 1946, causing the serine (S) at amino acid position 649 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
