The c.3325G>A (p.G1109R) alteration is located in exon 16 (coding exon 15) of the SPOCD1 gene. This alteration results from a G to A substitution at nucleotide position 3325, causing the glycine (G) at amino acid position 1109 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
