Genes affected

KDM3B (HGNC:1337): (lysine demethylase 3B) Predicted to enable chromatin DNA binding activity; histone H3-methyl-lysine-9 demethylase activity; and transcription coregulator activity. Predicted to be involved in histone H3-K9 demethylation and regulation of transcription by RNA polymerase II. Located in nucleoplasm. Biomarker of acute lymphoblastic leukemia; breast cancer; colorectal cancer; and lung non-small cell carcinoma. [provided by Alliance of Genome Resources, Apr 2022]

The c.97G>C (p.A33P) alteration is located in exon 1 (coding exon 1) of the KDM3B gene. This alteration results from a G to C substitution at nucleotide position 97, causing the alanine (A) at amino acid position 33 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
