Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 10, 2023The c.433C>T (p.R145W) alteration is located in exon 4 (coding exon 4) of the LEXM gene. This alteration results from a C to T substitution at nucleotide position 433, causing the arginine (R) at amino acid position 145 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
