Collection Method: clinical testing

The c.176A>G (p.H59R) alteration is located in exon 3 (coding exon 3) of the SPRYD3 gene. This alteration results from a A to G substitution at nucleotide position 176, causing the histidine (H) at amino acid position 59 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
