Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 31, 2023The c.806C>A (p.T269N) alteration is located in exon 3 (coding exon 3) of the ALKBH4 gene. This alteration results from a C to A substitution at nucleotide position 806, causing the threonine (T) at amino acid position 269 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
