Collection Method: clinical testing

The c.449C>G (p.T150S) alteration is located in exon 6 (coding exon 3) of the CSRNP3 gene. This alteration results from a C to G substitution at nucleotide position 449, causing the threonine (T) at amino acid position 150 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
