Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 24, 2023The c.31C>G (p.R11G) alteration is located in exon 1 (coding exon 1) of the CLYBL gene. This alteration results from a C to G substitution at nucleotide position 31, causing the arginine (R) at amino acid position 11 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
