Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 07, 2022The c.349A>C (p.T117P) alteration is located in exon 3 (coding exon 3) of the ATP9B gene. This alteration results from a A to C substitution at nucleotide position 349, causing the threonine (T) at amino acid position 117 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
