Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 10, 2024The c.1708G>A (p.V570I) alteration is located in exon 2 (coding exon 2) of the LRFN1 gene. This alteration results from a G to A substitution at nucleotide position 1708, causing the valine (V) at amino acid position 570 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
