Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 10, 2022The c.442G>A (p.E148K) 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 442, causing the glutamic acid (E) at amino acid position 148 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
