1. The motor function (MRCSS and 6MWT) and CTG repeat length of DMPK significantly correlated with LV diastolic dysfunction in patients with myotonic dystrophy type 1. PMID: 30094526
2. Variant repeats might explain a part of the phenotypic variability in a small percent of myotonic dystrophy type 1 patients and likely display a stabilizing effect on the meiotic instability of DMPK expanded alleles PMID: 28942489
3. Haplotype analysis using various polymorphic-markers in proximity to DMPK gene indicates that a single founder mutation originates myotonic dystrophy type 1 in Mexico; however, Y-STR haplogroups data and the presence of pre-mutated and large normal alleles in Amerindians support the hypothesis that both European and Amerindian ancestral chromosomes might have introduced the disease to the Mexican population. PMID: 29054426
4. Patients with myotonic dystrophy type 1 (DM1) may have a slight decrease in renal function that cannot be explained by a higher occurrence of risk factors for renal failure such as diabetes, hypertension or age. In addition, there was no correlation between CTG repeats, a marker of disease severity, and renal function. PMID: 29029879
5. Interruptions within the DMPK expanded alleles could also interfere with the chromatin structure, the transcriptional activity of the Myotonic dystrophy type 1 (DM1) locus and the interaction with RNA CUG-binding proteins PMID: 27991661
6.

10. findings thus suggest that nuclear retention may be a common feature of regulation of DMPK RNA expression. The typical forced nuclear residence of expanded DMPK transcripts affects this regulation in tissues of DM1 patients, but not through hyperadenylation. PMID: 28435090
11. Data, including data from studies on synthetic RNA modeling RNA repeat expansions found in patients with Huntington's disease (mRNA for exon 1 of Huntingtin protein) and myotonic dystrophy type 1 (mRNA for 3prime untranslated region of dystrophia myotonica-protein kinase), suggest internal loops of r(3xCAG) are stabilized by one-hydrogen bond AA pairs, while those of r(3xCUG) prefer one- or two-hydrogen bond UU pairs.

15. Sense DMPK RNA foci clearly co-localize with MBNL1 and MBNL2 proteins and accumulate in myotonic dystrophy 1 tissues during development. PMID: 26339785
16. This study supports the idea that genetic abnormalities in DM1mainly target the white matter, but gray matter involvement is also crucial in determining the clinical characteristics of myotonic dystrophy type 1. PMID: 26214024
17. that genome modification may be used to generate genetically modified progenitor cells as a first step toward autologous cell transfer therapy for Myotonic dystrophy type 1 PMID: 25702800
18. miR-206 and miR-148a regulate the DMPK transcript and may functionally cooperate. PMID: 26304544
