Genes affected

RNF146 (HGNC:21336): (ring finger protein 146) Enables poly-ADP-D-ribose binding activity and ubiquitin-protein transferase activity. Involved in positive regulation of canonical Wnt signaling pathway; protein ubiquitination; and ubiquitin-dependent protein catabolic process. Located in cytosol; nucleoplasm; and plasma membrane.

Ambry Genetics

Jan 09, 2024

The c.677A>G (p.D226G) alteration is located in exon 3 (coding exon 2) of the RNF146 gene. This alteration results from a A to G substitution at nucleotide position 677, causing the aspartic acid (D) at amino acid position 226 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
