Genes affected

MAZ (HGNC:6914): (MYC associated zinc finger protein) Enables DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in several processes, including regulation of gene expression; regulation of signal transduction; and transcription by RNA polymerase II. Predicted to be located in cytoplasm and nucleus.

The c.1470G>C (p.Q490H) alteration is located in exon 5 (coding exon 5) of the MAZ gene. This alteration results from a G to C substitution at nucleotide position 1470, causing the glutamine (Q) at amino acid position 490 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
