Abstract:
The porcine RN locus affects muscle glycogen content and meat
quality. We previously mapped the RN locus to chromosome 15.
This study describes the identification of polymorphisms for four
class I and four class II markers located in the RN region.
Resource families were genotyped with F-SSCP markers (fluorescent
single strand conformation polymorphism) and microsatellite markers.
Subsequent multipoint linkage analysis revealed the order
FN1-IGFBP5-S1000-S1001-IL8RB-VIL1-RN-Sw936-Sw906. The
gene order is identical to the previously reported porcine RH map
of the same region. The described map will facilitate positional
cloning of the RN gene.

Résumé:
Cartographie génétique de la région de RN chez le porc.
Le gène RN influence le taux de glycogène musculaire et la
qualité de la viande chez le porc. Il a été cartographié sur le
chromosome 15. Cette étude présente la cartographie de quatre
marqueurs SSCP (Polymorphisme de Conformation Simple Brin) et de
quatre microsatellites situés à proximité de RN. L'analyse
multipoint a permis de montrer que chez le porc l'ordre de ces
marqueurs,
FN1-IGFBP5-S1000-S1001-IL8RB-VIL1-RN-Sw936-Sw906, est
identique à celui chez l'homme et la souris. Le positionnement de
RN relativement aux marqueurs proches facilitera l'identification
du gène responsable par clonage positionnel.
