Submissions by phenotype

Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 02, 2024The p.P554L variant (also known as c.1661C>T), located in coding exon 11 of the LMF1 gene, results from a C to T substitution at nucleotide position 1661. The proline at codon 554 is replaced by leucine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Based on the available evidence, the clinical significance of this variant remains unclear. -
