The c.278G>A (p.R93K) alteration is located in exon 1 (coding exon 1) of the PDZRN4 gene. This alteration results from a G to A substitution at nucleotide position 278, causing the arginine (R) at amino acid position 93 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
