Feb 28, 2024

The c.50G>A (p.R17H) alteration is located in exon 1 (coding exon 1) of the LRRC37A2 gene. This alteration results from a G to A substitution at nucleotide position 50, causing the arginine (R) at amino acid position 17 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
