Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 31, 2023The c.790C>A (p.R264S) 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 790, causing the arginine (R) at amino acid position 264 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
