Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.688G>A (p.A230T) alteration is located in exon 4 (coding exon 4) of the NRIP2 gene. This alteration results from a G to A substitution at nucleotide position 688, causing the alanine (A) at amino acid position 230 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
