Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.940C>T (p.R314W) alteration is located in exon 11 (coding exon 11) of the NRK gene. This alteration results from a C to T substitution at nucleotide position 940, causing the arginine (R) at amino acid position 314 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
