The c.2340C>A (p.N780K) alteration is located in exon 4 (coding exon 4) of the SPATA31D3 gene. This alteration results from a C to A substitution at nucleotide position 2340, causing the asparagine (N) at amino acid position 780 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
