Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 31, 2023The c.604G>A (p.G202S) alteration is located in exon 3 (coding exon 2) of the CTU1 gene. This alteration results from a G to A substitution at nucleotide position 604, causing the glycine (G) at amino acid position 202 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
