Nov 26, 2024

The c.109C>G (p.L37V) alteration is located in exon 1 (coding exon 1) of the NCLN gene. This alteration results from a C to G substitution at nucleotide position 109, causing the leucine (L) at amino acid position 37 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
