Collection Method:clinical testing

The c.1513C>G (p.R505G) alteration is located in exon 14 (coding exon 13) of the SGPL1 gene. This alteration results from a C to G substitution at nucleotide position 1513, causing the arginine (R) at amino acid position 505 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
