The c.834C>A (p.N278K) alteration is located in exon 4 (coding exon 4) of the SDR9C7 gene. This alteration results from a C to A substitution at nucleotide position 834, causing the asparagine (N) at amino acid position 278 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
