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]

Collection Method: clinical testing

The c.221C>T (p.P74L) alteration is located in exon 3 (coding exon 1) of the KDM4D gene. This alteration results from a C to T substitution at nucleotide position 221, causing the proline (P) at amino acid position 74 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
