Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 04, 2024The c.1898G>A (p.R633H) alteration is located in exon 11 (coding exon 10) of the DQX1 gene. This alteration results from a G to A substitution at nucleotide position 1898, causing the arginine (R) at amino acid position 633 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
