Ambry Genetics

Oct 27, 2022

The c.903T>A (p.D301E) alteration is located in exon 8 (coding exon 7) of the CRISPLD1 gene. This alteration results from a T to A substitution at nucleotide position 903, causing the aspartic acid (D) at amino acid position 301 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
