Collection Method: clinical testing

The c.379T>A (p.S127T) alteration is located in exon 3 (coding exon 3) of the PARD3B gene. This alteration results from a T to A substitution at nucleotide position 379, causing the serine (S) at amino acid position 127 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
