Submissions by phenotype

Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2021The c.1637C>G (p.P546R) alteration is located in exon 11 (coding exon 11) of the LMF1 gene. This alteration results from a C to G substitution at nucleotide position 1637, causing the proline (P) at amino acid position 546 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
