The c.2335C>T (p.R779W) alteration is located in exon 1 (coding exon 1) of the LRRC37A gene. This alteration results from a C to T substitution at nucleotide position 2335, causing the arginine (R) at amino acid position 779 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
