The c.1450C>T (p.R484W) alteration is located in exon 11 (coding exon 10) of the LARGE2 gene. This alteration results from a C to T substitution at nucleotide position 1450, causing the arginine (R) at amino acid position 484 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
