Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 25, 2024The c.1472C>T (p.S491L) alteration is located in exon 7 (coding exon 7) of the LONRF2 gene. This alteration results from a C to T substitution at nucleotide position 1472, causing the serine (S) at amino acid position 491 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
