Collection Method: clinical testing

The c.245G>A (p.R82H) alteration is located in exon 2 (coding exon 2) of the LRRC3C gene. This alteration results from a G to A substitution at nucleotide position 245, causing the arginine (R) at amino acid position 82 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
