The c.317G>A (p.S106N) alteration is located in exon 3 (coding exon 3) of the SPATA33 gene. This alteration results from a G to A substitution at nucleotide position 317, causing the serine (S) at amino acid position 106 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
