The c.376T>G (p.L126V) alteration is located in exon 4 (coding exon 4) of the OLFM3 gene. This alteration results from a T to G substitution at nucleotide position 376, causing the leucine (L) at amino acid position 126 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
