Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 01, 2024The c.2152G>A (p.G718S) alteration is located in exon 12 (coding exon 12) of the LONRF2 gene. This alteration results from a G to A substitution at nucleotide position 2152, causing the glycine (G) at amino acid position 718 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
