Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2022The c.2027T>C (p.L676S) alteration is located in exon 11 (coding exon 11) of the LONRF2 gene. This alteration results from a T to C substitution at nucleotide position 2027, causing the leucine (L) at amino acid position 676 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
