Ambry Genetics

Nov 30, 2022

The c.835G>A (p.A279T) alteration is located in exon 7 (coding exon 6) of the LMNTD1 gene. This alteration results from a G to A substitution at nucleotide position 835, causing the alanine (A) at amino acid position 279 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
