Ambry Genetics

Dec 14, 2022

The c.1080T>G (p.D360E) alteration is located in exon 5 (coding exon 4) of the LNX2 gene. This alteration results from a T to G substitution at nucleotide position 1080, causing the aspartic acid (D) at amino acid position 360 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
