Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 04, 2024The c.1575C>A (p.D525E) alteration is located in exon 9 (coding exon 8) of the DQX1 gene. This alteration results from a C to A substitution at nucleotide position 1575, causing the aspartic acid (D) at amino acid position 525 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
