Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2022The c.773G>A (p.R258H) alteration is located in exon 3 (coding exon 3) of the ALKBH4 gene. This alteration results from a G to A substitution at nucleotide position 773, causing the arginine (R) at amino acid position 258 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
