Genes affected

MEX3C (HGNC:28040): (mex-3 RNA binding family member C) This gene encodes a member of a family of proteins with two K homology (KH) RNA-binding domains and a C-terminal RING-finger domain. The protein interacts with mRNA via the KH domains, and the protein shuttles between the nucleus and cytoplasm. Polymorphisms in this gene may contribute to hypertension.

The c.985G>A (p.V329I) alteration is located in exon 2 (coding exon 2) of the MEX3C gene. This alteration results from a G to A substitution at nucleotide position 985, causing the valine (V) at amino acid position 329 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
