Ambry Genetics

Feb 11, 2022

The c.4766C>T (p.T1589I) alteration is located in exon 12 (coding exon 10) of the LRRC37A3 gene. This alteration results from a C to T substitution at nucleotide position 4766, causing the threonine (T) at amino acid position 1589 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
