Genes affected

MAF1 (HGNC:24966): (MAF1 homolog, negative regulator of RNA polymerase III) This gene encodes a protein that is similar to Maf1, a Saccharomyces cerevisiae protein highly conserved in eukaryotic cells. Yeast Maf1 is a negative effector of RNA polymerase III (Pol III). It responds to changes in the cellular environment and represses pol III transcription. Biochemical studies identified the initiation factor TFIIIB as a target for Maf1-dependent repression. [provided by RefSeq, Jul 2008]

SHARPIN (HGNC:25321): (SHANK associated RH domain interactor) Enables polyubiquitin modification-dependent protein binding activity. Involved in protein linear polyubiquitination and regulation of signal transduction. Located in cytosol. Part of LUBAC complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.736A>G (p.M246V) alteration is located in exon 7 (coding exon 6) of the MAF1 gene. This alteration results from a A to G substitution at nucleotide position 736, causing the methionine (M) at amino acid position 246 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
