Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 31, 2023The c.2027T>C (p.L676P) alteration is located in exon 12 (coding exon 11) of the DQX1 gene. This alteration results from a T to C substitution at nucleotide position 2027, causing the leucine (L) at amino acid position 676 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
