Genes affected

MEX3B (HGNC:25297): (mex-3 RNA binding family member B) This gene encodes an RNA-binding phosphoprotein that is part of the MEX3 (muscle excess 3) family of translational regulators. The encoded protein contains N-terminal nuclear export and nuclear localization signals and is exported from the cytoplasm to the nucleus. The protein binds to RNA via two KH domains and also colocalizes with MEX3A, Dcp1A decapping factor and Argonaute proteins within P (processing) bodies. [provided by RefSeq, Oct 2012]

The c.1064G>A (p.G355D) alteration is located in exon 2 (coding exon 2) of the MEX3B gene. This alteration results from a G to A substitution at nucleotide position 1064, causing the glycine (G) at amino acid position 355 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
