Genes affected

ZFAND2B (HGNC:25206): (zinc finger AN1-type containing 2B) This gene encodes a protein containing AN1-type zinc-fingers and ubiquitin-interacting motifs. The encoded protein likely associates with the proteosome to stimulate the degradation of toxic or misfolded proteins. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Aug 2012]

The c.317G>A (p.R106Q) alteration is located in exon 4 (coding exon 4) of the ZFAND2B gene. This alteration results from a G to A substitution at nucleotide position 317, causing the arginine (R) at amino acid position 106 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
