Collection Method: clinical testing

The c.161C>G (p.T54S) alteration is located in exon 1 (coding exon 1) of the PNRC1 gene. This alteration results from a C to G substitution at nucleotide position 161, causing the threonine (T) at amino acid position 54 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
