The c.398C>T (p.T133I) alteration is located in exon 4 (coding exon 4) of the PARD3B gene. This alteration results from a C to T substitution at nucleotide position 398, causing the threonine (T) at amino acid position 133 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
