Ambry Genetics

Mar 24, 2023

The c.259C>T (p.H87Y) alteration is located in exon 4 (coding exon 3) of the LRRC20 gene. This alteration results from a C to T substitution at nucleotide position 259, causing the histidine (H) at amino acid position 87 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
