The c.2993C>G (p.T998R) alteration is located in exon 7 (coding exon 7) of the LRRC37A gene. This alteration results from a C to G substitution at nucleotide position 2993, causing the threonine (T) at amino acid position 998 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
