Genes affected

KDM3A (HGNC:20815): (lysine demethylase 3A) Enables androgen receptor binding activity; histone H3-methyl-lysine-9 demethylase activity; and iron ion binding activity. Involved in several processes, including androgen receptor signaling pathway; formaldehyde biosynthetic process; and histone H3-K9 demethylation. Located in nucleoplasm. Implicated in cervical cancer and colon cancer. Biomarker of Ewing sarcoma; hepatocellular carcinoma; nasopharynx carcinoma; and prostate cancer. [provided by Alliance of Genome Resources, Apr 2022]

The c.440T>G (p.L147W) alteration is located in exon 4 (coding exon 3) of the KDM3A gene. This alteration results from a T to G substitution at nucleotide position 440, causing the leucine (L) at amino acid position 147 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
