Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 22, 2021The c.1510C>T (p.R504W) alteration is located in exon 8 (coding exon 8) of the LGI3 gene. This alteration results from a C to T substitution at nucleotide position 1510, causing the arginine (R) at amino acid position 504 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
