Genes affected

ZRANB1 (HGNC:18224): (zinc finger RANBP2-type containing 1) Enables K63-linked polyubiquitin modification-dependent protein binding activity and thiol-dependent deubiquitinase. Involved in several processes, including positive regulation of Wnt signaling pathway; protein deubiquitination; and regulation of cell morphogenesis. Located in cytosol and nucleoplasm.

ZRANB1 links:

CTBP2 (HGNC:2495): (C-terminal binding protein 2) This gene produces alternative transcripts encoding two distinct proteins. One protein is a transcriptional repressor, while the other isoform is a major component of specialized synapses known as synaptic ribbons. Both proteins contain a NAD+ binding domain similar to NAD+-dependent 2-hydroxyacid dehydrogenases. A portion of the 3' untranslated region was used to map this gene to chromosome 21q21.3; however, it was noted that similar loci elsewhere in the genome are likely. Blast analysis shows that this gene is present on chromosome 10. Several transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Feb 2014]

The c.2071C>T (p.R691W) alteration is located in exon 9 (coding exon 9) of the ZRANB1 gene. This alteration results from a C to T substitution at nucleotide position 2071, causing the arginine (R) at amino acid position 691 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
