Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 11, 2022The c.189G>C (p.R63S) alteration is located in exon 1 (coding exon 1) of the LRRC18 gene. This alteration results from a G to C substitution at nucleotide position 189, causing the arginine (R) at amino acid position 63 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
