Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 12, 2023The c.631C>G (p.R211G) alteration is located in exon 3 (coding exon 2) of the CTU1 gene. This alteration results from a C to G substitution at nucleotide position 631, causing the arginine (R) at amino acid position 211 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
