The c.2252T>G (p.L751R) alteration is located in exon 1 (coding exon 1) of the LRRC37A2 gene. This alteration results from a T to G substitution at nucleotide position 2252, causing the leucine (L) at amino acid position 751 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
