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.296G>A (p.R99Q) alteration is located in exon 3 (coding exon 2) of the KDM3A gene. This alteration results from a G to A substitution at nucleotide position 296, causing the arginine (R) at amino acid position 99 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
