Collection Method: clinical testing

The c.784A>G (p.I262V) alteration is located in exon 7 (coding exon 4) of the CSRNP3 gene. This alteration results from a A to G substitution at nucleotide position 784, causing the isoleucine (I) at amino acid position 262 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
