Collection Method: clinical testing

The c.266C>A (p.T89N) alteration is located in exon 1 (coding exon 1) of the PNRC1 gene. This alteration results from a C to A substitution at nucleotide position 266, causing the threonine (T) at amino acid position 89 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
