Ambry Genetics

Apr 12, 2023

The c.2011G>T (p.D671Y) alteration is located in exon 5 (coding exon 5) of the PDZD8 gene. This alteration results from a G to T substitution at nucleotide position 2011, causing the aspartic acid (D) at amino acid position 671 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
