The c.1205G>C (p.G402A) alteration is located in exon 5 (coding exon 3) of the SPARCL1 gene. This alteration results from a G to C substitution at nucleotide position 1205, causing the glycine (G) at amino acid position 402 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
