Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2021The c.2008C>T (p.R670C) 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 2008, causing the arginine (R) at amino acid position 670 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
