Myotonic Dystrophy Type 1 (DM1) – DMPK Repeat Analysis in London
Myotonic Dystrophy Type 1 (DM1) DMPK repeat analysis is available at South Kensington Medical and Dental, our CQC-registered clinic in South Kensington, London SW7. 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 5 weeks. A referral from a clinical neurologist or clinical geneticist is required before this test can be ordered.
Myotonic Dystrophy Type 1 (DM1) is the most common adult-onset muscular dystrophy, caused by an expansion of CTG trinucleotide repeats in the DMPK gene on chromosome 19q. This PCR-based test measures the number of CTG repeats to determine whether an individual carries the pathogenic expansion.
Who Should Consider DM1 DMPK Repeat Testing?
Individuals with myotonia (difficulty relaxing muscles after contraction), progressive muscle weakness particularly of the face, neck, and distal limbs, cataracts, cardiac conduction defects, or excessive daytime sleepiness. Family members of confirmed DM1 patients seeking predictive testing. Couples planning a family, as DM1 shows anticipation (increasing severity in successive generations).
Normal alleles have 5-34 CTG repeats. Premutation alleles (35-49 repeats) may expand in future generations. Full mutation alleles (50 or more repeats) cause disease. Congenital DM1 typically involves very large expansions (over 1000 repeats). Genetic counselling is essential before and after testing due to implications of anticipation.
A trained nurse collects the blood sample by standard venepuncture at our clinic on Old Brompton Road, directly opposite South Kensington tube station (Piccadilly, Circle, and District lines). A referral from a clinical neurologist or clinical geneticist is required — please call 020 7183 2362 to arrange.
