Individuals with ETV6 thrombocytopenia and predisposition to leukemia most often present with a lifelong history of thrombocytopenia, which is usually in the mild to moderate range. No syndromic features or associations are consistently shared across pedigrees. Affected individuals also have a moderate risk of developing a hematologic malignancy (with B-cell acute lymphoblastic leukemia [B-ALL] being the most common) and possibly other malignant solid tumors, particularly colorectal cancer. [from GeneReviews]

Autosomal recessive agammaglobulinemia-8B (AGM8B) is characterized by onset of recurrent infections in early childhood. Laboratory studies of affected individuals show decreased circulating immunoglobulins and decreased peripheral B cells. More variable features may include dysmorphic facies and subtle abnormalities of other immune cells, such as T cells. One patient who developed childhood B-cell acute lymphocytic leukemia (B-ALL) has been described (summary by Ben-Ali et al., 2017). [from OMIM]
