Collection Method: clinical testing

The c.2434G>A (p.G812R) alteration is located in exon 17 (coding exon 16) of the SPICE1 gene. This alteration results from a G to A substitution at nucleotide position 2434, causing the glycine (G) at amino acid position 812 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
