Popis: | The jerker mutation causes degeneration of cochlea and vestibular sensoryhair cells in mice. A frame-shift mutation in the actin bundling gene Espin (Espn) leads to hair bundle defects bydisrupting the actin filament assemblyin stereocilia. Previously , jerker was mapped to distal mouse chromosome 4. Here, analyzing 2536 informative meioses derived from two intersubspecific intercrosses, we localize jerker to a 0:51 � 0:14 cM interval on chromosome 4. The following order and distances of genes and markers were determined: D4Mit180—0:44 � 0:13 cM—Hes2, Espn je —0:08 � 0:06 cM—D4Mit356—0:28 � 0: 1c M—D4Mit208. A 300 kb physical bacterial artificial chromosome (BAC) contig was generated containing the Espn je locus. The human homologous region maps to 1p36.31. We present a detailed high-resolution genetic and physical map of markers located at distal chromosome 4 and demonstrate concordance of Espn with jerker. 2002 Elsevier Science (USA).
