Genes affected
KDM4A (HGNC:22978): (lysine demethylase 4A) This gene is a member of the Jumonji domain 2 (JMJD2) family and encodes a protein containing a JmjN domain, a JmjC domain, a JD2H domain, two TUDOR domains, and two PHD-type zinc fingers. This nuclear protein functions as a trimethylation-specific demethylase, converting specific trimethylated histone residues to the dimethylated form, and as a transcriptional repressor.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 14, 2024The c.2921G>C (p.G974A) alteration is located in exon 20 (coding exon 19) of the KDM4A gene. This alteration results from a G to C substitution at nucleotide position 2921, causing the glycine (G) at amino acid position 974 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
