Ambry Genetics

Jun 02, 2023

The c.163G>T (p.D55Y) alteration is located in exon 2 (coding exon 1) of the CRISPLD2 gene. This alteration results from a G to T substitution at nucleotide position 163, causing the aspartic acid (D) at amino acid position 55 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
