Jan 23, 2024

The c.626G>A (p.R209H) alteration is located in exon 4 (coding exon 4) of the LRRC75B gene. This alteration results from a G to A substitution at nucleotide position 626, causing the arginine (R) at amino acid position 209 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
