Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 12, 2023The c.589A>C (p.N197H) alteration is located in exon 1 (coding exon 1) of the LRRC18 gene. This alteration results from a A to C substitution at nucleotide position 589, causing the asparagine (N) at amino acid position 197 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
