Ambry Genetics

Dec 13, 2023

The c.907A>G (p.K303E) alteration is located in exon 4 (coding exon 4) of the PDZRN4 gene. This alteration results from a A to G substitution at nucleotide position 907, causing the lysine (K) at amino acid position 303 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
