The c.787G>A (p.V263I) alteration is located in exon 7 (coding exon 7) of the PARD3B gene. This alteration results from a G to A substitution at nucleotide position 787, causing the valine (V) at amino acid position 263 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
