Ambry Genetics

May 08, 2024

The c.1637C>T (p.T546M) alteration is located in exon 14 (coding exon 14) of the LRRC40 gene. This alteration results from a C to T substitution at nucleotide position 1637, causing the threonine (T) at amino acid position 546 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
