Ambry Genetics

Apr 12, 2022

The c.902A>T (p.D301V) alteration is located in exon 8 (coding exon 7) of the CRISPLD1 gene. This alteration results from a A to T substitution at nucleotide position 902, causing the aspartic acid (D) at amino acid position 301 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
