Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2023The c.157G>A (p.V53M) alteration is located in exon 2 (coding exon 1) of the LRFN3 gene. This alteration results from a G to A substitution at nucleotide position 157, causing the valine (V) at amino acid position 53 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
