Feb 14, 2023

The c.844C>G (p.R282G) alteration is located in exon 3 (coding exon 2) of the LRRC14 gene. This alteration results from a C to G substitution at nucleotide position 844, causing the arginine (R) at amino acid position 282 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
