\nThe type 1 neuropathy (LPN1) in Leonberger is caused by a mutation in the ARHGEF10 gene. The disease starts at the age of 2-4 year (early onset) and shows a severe progression. The causative mutation causes around 11% of all polyneuropathy cases in the Leonberger breed.
\nRecently, a mutation in the GJA9 gene could be identified to cause a second type of neuropathy in Leonberger (LPN2). The GJA9 protein is member of the connexin gap junction family whose members have emerged as important components of peripheral myelinated nerve fibers. The average age of onset of LPN2 is 6 years. LPN2 causes around 21% of all polyneuropathy cases in the Leonberger breed.
\nOther aetiologic mutations exist.
