Ambry Genetics

Nov 08, 2024

The c.22G>A (p.A8T) alteration is located in exon 1 (coding exon 1) of the LEXM gene. This alteration results from a G to A substitution at nucleotide position 22, causing the alanine (A) at amino acid position 8 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
