The c.374C>A (p.T125N) alteration is located in exon 3 (coding exon 3) of the PARD3B gene. This alteration results from a C to A substitution at nucleotide position 374, causing the threonine (T) at amino acid position 125 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
