Gene: Cybam1Sdi (cytochrome b-245 alpha chain;mutant 1,Sdi) Rattus norvegicus
Symbol: Cybam1Sdi
Name: cytochrome b-245 alpha chain;mutant 1,Sdi
RGD ID: 13209000
Description: This allele was identified in the MES rat strain that spontaneously develops severe blood eosinophilia as a hereditary trait. It carries a deletion of four nucleotides, including the 5' splice donor GpT of intron 4 of the Cyba gene.
ASSOCIATED WITH absent otoliths; decreased NAD(P)H oxidase activity; increased eosinophil cell number; ASSOCIATED WITH Eosinophilia
Type: allele  of Cyba  
Previously known as: Cyba^[m1Sdi]; Cybam1Sdi
Is Marker For: Strains:   MES/Slc  
Latest Assembly: mRatBN7.2 - mRatBN7.2 Assembly
Position: No map positions available.
