Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 10, 2021The c.2066C>T (p.P689L) alteration is located in exon 11 (coding exon 11) of the LONRF2 gene. This alteration results from a C to T substitution at nucleotide position 2066, causing the proline (P) at amino acid position 689 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
