The c.1741C>G (p.R581G) alteration is located in exon 15 (coding exon 15) of the LRRC40 gene. This alteration results from a C to G substitution at nucleotide position 1741, causing the arginine (R) at amino acid position 581 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
