The c.774C>G (p.D258E) alteration is located in exon 2 (coding exon 2) of the SP9 gene. This alteration results from a C to G substitution at nucleotide position 774, causing the aspartic acid (D) at amino acid position 258 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
