Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.143G>A (p.R48H) alteration is located in exon 1 (coding exon 1) of the LRRC18 gene. This alteration results from a G to A substitution at nucleotide position 143, causing the arginine (R) at amino acid position 48 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
