The c.1111C>G (p.L371V) alteration is located in exon 7 (coding exon 6) of the OSGEPL1 gene. This alteration results from a C to G substitution at nucleotide position 1111, causing the leucine (L) at amino acid position 371 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
