Part Description

LP19787-8   DMPK gene.CTG repeats
The DMPK gene (dystrophia myotonica-protein kinase) [HGNC Gene ID:2933] is located on chromosome 19q13.3. The protein encoded by this gene is a serine-threonine kinase that is closely related to other kinases that interact with members of the Rho family of small GTPases. Substrates for this enzyme include myogenin, the beta-subunit of the L-type calcium channels, and phospholemman. The 3' untranslated region of this gene contains 5-37 copies of a CTG trinucleotide repeat. Expansion of this unstable motif to 50-5,000 copies causes myotonic dystrophy type I, which increases in severity with increasing repeat element copy number. Repeat expansion is associated with condensation of local chromatin structure that disrupts the expression of genes in this region. Several alternatively spliced transcript variants of this gene have been described, but the full-length nature of some of these variants has not been determined.

Change Reason
Changed Property from Arb (Arbitrary) to 'Threshold' since the results (e.g. positive, intermediate, negative) is based on the number of nucleotide repeats. Moved term from Class MOLPATH.TRINUC to MOLPATH.NUCREPEAT, a Class used to group together observations for nucleotide repeats.; The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
