Strain name: C57BL/6JSfdAnu-Ncaph2nes/AnuApb
Nickname: Nessy
Strain designation name: C57BL/6JSfdAnu-Ncaph2nes/AnuApb
Strain Types Mutant strain
Genetic Details Chemically induced : ENU
Mode of Inheritance Recessive
1.  Affected Gene Name: non-SMC condensin II complex, subunit H2  
Chromosome 15
Affected Gene Symbol Ncaph2
Protein expression of altered gene: Unknown
Genetic alteration of gene: ENU induced mutation. T⇒A in exon 1, nucleotide ,I15N (long form), S13T (short form) (note that there are two ATG transcriptional start sites for this gene, resulting in three alternate amino acid sequences for exon 1).
Location on chromosome (bp): 89186150-89203257 bp, + strand (From VEGA annotation of NCBI Build 37)

Mutant Construction Technique None
Phenotype Homozygous State The nessy mouse has a defect in T lymphocyte development that decreases circulating T cell numbers, increases their expression of the activation/memory marker CD44, and dramatically decreases the numbers of CD4(+)CD8(+) thymocytes and their immediate DN4 precursors. Thymic T cell differentiation defect at DN-DP transition, low peripheral T cell numbers, remaining cells all CD44high, Two fold more gd T cells, Defect resembles mice with exaggerated TCR signalling due to defects in c-cbl and slap proteins and defects in cbl plus cbl-b. No defect in B cells. Homozygotes grow at normal rate, size and are fertile. Intrinsic to T cells. Despite the ubiquitous expression and role of condensins, kleisin beta(nes/nes) mice were viable, fertile, and showed no defects even in the parallel pathway of B cell lymphocyte differentiation.
