Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.1091T>C (p.L364P) alteration is located in exon 5 (coding exon 5) of the LONRF2 gene. This alteration results from a T to C substitution at nucleotide position 1091, causing the leucine (L) at amino acid position 364 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
