Genes affected
KDM4B (HGNC:29136): (lysine demethylase 4B) Enables histone H3-methyl-lysine-36 demethylase activity and histone H3-methyl-lysine-9 demethylase activity. Involved in histone H3-K36 demethylation and histone H3-K9 demethylation. Located in cytosol and nucleoplasm. Implicated in autosomal dominant non-syndromic intellectual disability; breast cancer; colorectal cancer; malignant peripheral nerve sheath tumor; and stomach cancer. Biomarker of several diseases, including alopecia areata; lung cancer; medulloblastoma; prostate cancer; and stomach cancer. [provided by Alliance of Genome Resources, Apr 2022]

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Nov 17, 2021 | The c.169C>T (p.R57W) alteration is located in exon 4 (coding exon 2) of the KDM4B gene. This alteration results from a C to T substitution at nucleotide position 169, causing the arginine (R) at amino acid position 57 to be replaced by a tryptophan (W). The KDM4B c.169C>T alteration was flagged as a low confidence call in the Genome Aggregation Database (gnomAD). This amino acid position is highly conserved in available vertebrate species. This missense alteration is located in a region that has a low rate of benign missense variation (Lek, 2016; Firth, 2009). The in silico prediction for this alteration is inconclusive. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
not provided Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | GeneDx | Jun 13, 2024 | Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis supports that this missense variant has a deleterious effect on protein structure/function; Has not been previously published as pathogenic or benign to our knowledge - |
