The c.820G>T (p.V274L) alteration is located in exon 2 (coding exon 2) of the SP9 gene. This alteration results from a G to T substitution at nucleotide position 820, causing the valine (V) at amino acid position 274 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
