Genetics (molecular biology) and Meniere's disease.

ABSTRACT

COCH is not the FMD gene detected in our linkage study; furthermore, COCH and FMD are not allelic. The indications are that FMD is heterogenetic. The linkage analysis points to the possibility of one FMD mutation in one of the neighboring candidate genes on chromosome 14, and, with anticipation, possibly a triple repeat amplification. Recently, the myotonic dystrophy type 2 locus has been shown to contain an expanded tetranucleotide repeat [46], so the search for a similar repeat on 14q is indicated.
