The c.1036T>C (p.W346R) alteration is located in exon 9 (coding exon 9) of the LRGUK gene. This alteration results from a T to C substitution at nucleotide position 1036, causing the tryptophan (W) at amino acid position 346 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
