Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 23, 2023The c.398C>T (p.T133M) alteration is located in exon 4 (coding exon 4) of the LSMEM2 gene. This alteration results from a C to T substitution at nucleotide position 398, causing the threonine (T) at amino acid position 133 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
