Collection Method: clinical testing

The c.1006G>A (p.G336S) alteration is located in exon 12 (coding exon 11) of the OC90 gene. This alteration results from a G to A substitution at nucleotide position 1006, causing the glycine (G) at amino acid position 336 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
