Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 05, 2024The c.1497C>A (p.D499E) alteration is located in exon 2 (coding exon 2) of the LRFN1 gene. This alteration results from a C to A substitution at nucleotide position 1497, causing the aspartic acid (D) at amino acid position 499 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
