Ambry Genetics

May 30, 2023

The c.479A>C (p.N160T) alteration is located in exon 4 (coding exon 4) of the LRRC74A gene. This alteration results from a A to C substitution at nucleotide position 479, causing the asparagine (N) at amino acid position 160 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
