Hi, Thank you for posting your query. There are two common naturopathies that are hereditary in nature. The first one is called as HMSN- hereditary motor sensory neuropathy. In this condition, the weakness and numbness are more in legs, as compared to the hands. Thinning of muscles is also noted. The other type of inherited neuropathy is called as SAN- hereditary sensory autonomic neuropathy. In this condition, numbness is associated with autonomic symptoms such as postural giddiness, bladder symptoms, erectile dysfunction, etc. Motor weakness is not a feature in SAN. So, I feel they had a form of HMSN. I hope it helps. Please get back if you require any additional information. Wishing you good health, Chat Doctor. Ly/
