Genes affected

BCL11A (HGNC:13221): (BCL11 transcription factor A) This gene encodes a C2H2 type zinc-finger protein by its similarity to the mouse Bcl11a/Evi9 protein. The corresponding mouse gene is a common site of retroviral integration in myeloid leukemia, and may function as a leukemia disease gene, in part, through its interaction with BCL6. During hematopoietic cell differentiation, this gene is down-regulated. It is possibly involved in lymphoma pathogenesis since translocations associated with B-cell malignancies also deregulates its expression. Multiple transcript variants encoding several different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PM4: Nonframeshift variant in NON repetitive region in NM_022893.4. Strenght limited to Supporting due to length of the change: 1aa.
• PP5: Variant 2-60461136-G-GCCA is Pathogenic according to our data. Variant chr2-60461136-G-GCCA is described in ClinVar as [Pathogenic]. Clinvar id is 253304.Status of the report is no_assertion_criteria_provided, 0 stars.
