The c.460T>G (p.W154G) alteration is located in exon 1 (coding exon 1) of the PDZRN4 gene. This alteration results from a T to G substitution at nucleotide position 460, causing the tryptophan (W) at amino acid position 154 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
