Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 02, 2023The c.4046C>A (p.A1349E) alteration is located in exon 13 (coding exon 13) of the LMTK3 gene. This alteration results from a C to A substitution at nucleotide position 4046, causing the alanine (A) at amino acid position 1349 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
