Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 13, 2022The c.1036C>T (p.P346S) alteration is located in exon 3 (coding exon 2) of the CTU1 gene. This alteration results from a C to T substitution at nucleotide position 1036, causing the proline (P) at amino acid position 346 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
