Who Should Consider CMT1A PMP22 Duplication Testing?
Individuals with progressive distal muscle weakness and wasting, foot deformity (pes cavus), reduced reflexes, and sensory loss suggestive of hereditary motor and sensory neuropathy. Those with nerve conduction studies showing a demyelinating pattern. Family members of confirmed CMT1A patients seeking carrier or predictive testing.
CMT1A follows autosomal dominant inheritance, meaning each child of an affected parent has a 50% chance of inheriting the condition. Genetic counselling is recommended before and after testing to discuss implications for the individual and family members.
A trained nurse collects the blood sample by standard venepuncture at our clinic on Wimpole Street, a short walk from Bond Street and Oxford Circus stations. A referral from a clinical neurologist or clinical geneticist is required, please call 020 7183 0692 to arrange.
