Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 17, 2023The c.397C>T (p.R133W) alteration is located in exon 3 (coding exon 3) of the ALKBH4 gene. This alteration results from a C to T substitution at nucleotide position 397, causing the arginine (R) at amino acid position 133 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
