The c.575G>T (p.R192L) alteration is located in exon 2 (coding exon 2) of the LRRC3C gene. This alteration results from a G to T substitution at nucleotide position 575, causing the arginine (R) at amino acid position 192 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
