Genes affected

KDM4D (HGNC:25498): (lysine demethylase 4D) Enables histone H3-methyl-lysine-9 demethylase activity. Involved in histone H3-K9 demethylation. Acts upstream of or within several processes, including cellular response to ionizing radiation; positive regulation of chromatin binding activity; and positive regulation of double-strand break repair via nonhomologous end joining. Located in site of double-strand break. Biomarker of nephroblastoma. [provided by Alliance of Genome Resources, Apr 2022]

The c.296G>C (p.G99A) alteration is located in exon 3 (coding exon 1) of the KDM4D gene. This alteration results from a G to C substitution at nucleotide position 296, causing the glycine (G) at amino acid position 99 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
