The c.811C>T (p.R271W) alteration is located in exon 6 (coding exon 6) of the LAMP5 gene. This alteration results from a C to T substitution at nucleotide position 811, causing the arginine (R) at amino acid position 271 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
