Jan 04, 2022

The c.284G>A (p.R95Q) alteration is located in exon 2 (coding exon 2) of the LRRC75B gene. This alteration results from a G to A substitution at nucleotide position 284, causing the arginine (R) at amino acid position 95 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
