Part Description

LP33150-1   GJB2 gene
The GJB2 gene (gap junction protein, beta 2, 26kDa) [HGNC Gene ID:4284] is located on chromosome 13q11-q12. This gene encodes a member of the gap junction protein family. The gap junctions were first characterized by electron microscopy as regionally specialized structures on plasma membranes of contacting adherent cells. These structures were shown to consist of cell-to-cell channels that facilitate the transfer of ions and small molecules between cells. The gap junction proteins, also known as connexins, purified from fractions of enriched gap junctions from different tissues differ. According to sequence similarities at the nucleotide and amino acid levels, the gap junction proteins are divided into two categories, alpha and beta. Mutations in this gene are responsible for as much as 50% of pre-lingual, recessive deafness.

Change Reason
Based on LOINC Committee review (June 2016), "targeted" was added to the Component to clarify that this test is looking for a specific set of mutations as described in the LOINC User Guide under the Molecular Genetics section.; Based on LOINC Committee review (June 2019), updated the Property from "Prid" to "Find" and Scale from "Nar" to "Doc" to align with the current LOINC model for naming collections of information reported in narrative and/or structured formats.
