Description : In recessively inherited spinocerebellar ataxia of uncertain classification, Van Bogaert
and Martin (1974) and Spoendlin (1974) described optic and cochlear degeneration leading
to blindness and deafness. Presumably this was not the Refsum syndrome (266500), which
has similar manifestations. Koenig (2001) concluded that the same disorder was present
in the consanguineous Israeli family he studied with Bomont et al. (2000). An Israeli
uncle and niece were affected by an early-onset recessive ataxia and subsequently
developed hearing impairment and optic atrophy. Homozygosity over a 17-cM region allowed
demonstration of linkage at 6p23-p21 with a lod score of 3.25. *FIELD* RF 1. Bomont,
