Myotonic Dystrophy Type 2 (PROMM) – ZNF9 Repeat Analysis in London
Myotonic Dystrophy Type 2 (DM2/PROMM) ZNF9 (CNBP) repeat analysis is available at Wimpole Street Medical and Dental, our CQC-registered clinic in Marylebone, London W1G. This test is priced at £560. A £50 phlebotomy fee applies per visit for blood collection. It requires a venous blood sample, and results are typically available within 6 weeks. A referral from a clinical neurologist or clinical geneticist is required before this test can be ordered.
Myotonic Dystrophy Type 2 (DM2), also known as Proximal Myotonic Myopathy (PROMM), is caused by an expansion of CCTG tetranucleotide repeats in the CNBP (ZNF9) gene on chromosome 3q. This PCR-based test detects the pathogenic repeat expansion. DM2 is generally milder than DM1 and does not show significant anticipation.
Who Should Consider DM2 ZNF9 Repeat Testing?
Individuals with proximal muscle weakness, myotonia, muscle pain, cataracts, or cardiac conduction abnormalities where DM1 testing has been negative. Those with a family history of DM2 seeking predictive testing. DM2 typically presents later in life (third to sixth decade) with milder symptoms than DM1.
Normal alleles have up to 26 CCTG repeats. Pathogenic expansions range from approximately 75 to over 11,000 repeats. Unlike DM1, there is no congenital form of DM2 and the condition does not show significant anticipation. Genetic counselling is recommended to discuss inheritance and implications for family members.
A trained nurse collects the blood sample by standard venepuncture at our clinic on Wimpole Street, directly opposite Wimpole Street tube station (Piccadilly, Circle, and District lines). A referral from a clinical neurologist or clinical geneticist is required — please call 020 7183 0692 to arrange.
