Genes affected

CNST (HGNC:26486): (consortin, connexin sorting protein) Targeting of numerous transmembrane proteins to the cell surface is thought to depend on their recognition by cargo receptors that interact with the adaptor machinery for anterograde traffic at the distal end of the Golgi complex. Consortin (CNST) is an integral membrane protein that acts as a binding partner of connexins, the building blocks of gap junctions, and acts as a trans-Golgi network (TGN) receptor involved in connexin targeting to the plasma membrane and recycling from the cell surface (del Castillo et al., 2010 [PubMed 19864490]).[supplied by OMIM, Jun 2010]

Collection Method:clinical testing

The c.503T>C (p.L168P) alteration is located in exon 3 (coding exon 2) of the CNST gene. This alteration results from a T to C substitution at nucleotide position 503, causing the leucine (L) at amino acid position 168 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
