Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.40G>A (p.G14S) alteration is located in exon 4 (coding exon 1) of the CSRNP3 gene. This alteration results from a G to A substitution at nucleotide position 40, causing the glycine (G) at amino acid position 14 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
