OMIA:002386-9544 : OKT4 epitope deficiency in Macaca mulatta (Rhesus monkey)

Categories: Cellular phene

Possibly relevant human trait(s) and/or gene(s)s (MIM numbers): 613949 (trait) , 186940 (gene)

Links to MONDO diseases: No links.

Mendelian trait/disorder: yes

Mode of inheritance: Autosomal

Considered a defect: unknown

Key variant known: yes

Year key variant first reported: 2021

Cross-species summary: OKT monoclonal antibodies are widely used for the analysis of human peripheral blood T lymphocytes. OKT4 monoclonal antibodies react with OKT4 epitope of CD4 molecules of T-helper/inducer cells.

Molecular basis: Liu et al. (2021) "reported a case of hereditary deficiency of OKT4 epitope in an inbred Chinese rhesus macaque family. This epitope deficiency is due to cytosine to thymine transition and homozygote at the nucleotide position 793 of CD4 coding sequences, which leads to the replace of arginine at 265th position of CD4 molecule by tryptophan."

Genetic engineering: Unknown
Have human generated variants been created, e.g. through genetic engineering and gene editing

Variants

By default, variants are sorted chronologically by year of publication, to provide a historical perspective. Readers can re-sort on any column by clicking on the column header. Click it again to sort in a descending order. To create a multiple-field sort, hold down Shift while clicking on the second, third etc relevant column headers.

WARNING! Inclusion of a variant in this table does not automatically mean that it should be used for DNA testing. Anyone contemplating the use of any of these variants for DNA testing should examine critically the relevant evidence (especially in breeds other than the breed in which the variant was first described). If it is decided to proceed, the location and orientation of the variant sequence should be checked very carefully.

Since October 2021, OMIA includes a semiautomated lift-over pipeline to facilitate updates of genomic positions to a recent reference genome position. These changes to genomic positions are not always reflected in the ‘acknowledgements’ or ‘verbal description’ fields in this table.
