Species-specific name: feline alimentary T cell lymphoma; epitheliotropic intestinal T-Cell lymphomas

Species-specific symbol: EATL

Species-specific description: Kieslinger et al. (2021): "Analysis of 42 samples of feline T cell alimentary lymphoma reveals broad activation of STAT3 and STAT5B. Screening for known activating mutations in STAT3 or STAT5B identifies the presence of the STAT5B^N642H driver mutation in feline enteropathy-associated T cell lymphoma in 7 out of 42 (16.67%) samples in total. Regarding lymphoma subtypes, the majority of mutations with 5 out of 17 (29.41%) cases were found in feline enteropathy-associated lymphoma type II (EATL II)." IT IS IMPORTANT TO NOTE THAT THIS IS UNDERSTOOD TO BE A SOMATIC MUTATION, WHICH MEANS THAT THE VARIANT IS NOT INHERITED AND WILL NOT BE PASSED ON TO OFFSPRING.

Clinical features: A cat with EATL may present with a history of reduced or increased appetite, vomiting, lethargy, diarrhoea, constipation, and weight loss. Weight loss related to muscle wasting is the most common sign (Marsilio et al., 2023). The clinical findings in these cats may include abdominal pain or discomfort, muscle loss, diffusely thickened intestinal walls, enlarged mesenteric lymph nodes or masses within the abdomen. Clinical signs may be minimal or absent (Marsilio et al., 2023). IT thanks DVM student Lily Harford Sherringham, who provided the basis of this contribution in May 2023.

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.
