Genes affected
ALKBH4 (HGNC:21900): (alkB homolog 4, lysine demethylase) Enables 2-oxoglutarate-dependent dioxygenase activity and actin binding activity. Involved in actomyosin structure organization; cleavage furrow ingression; and protein demethylation. Located in contractile ring and midbody. [provided by Alliance of Genome Resources, Apr 2022]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 21, 2024The c.528G>C (p.W176C) alteration is located in exon 3 (coding exon 3) of the ALKBH4 gene. This alteration results from a G to C substitution at nucleotide position 528, causing the tryptophan (W) at amino acid position 176 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
