Genes affected

MLLT11 (HGNC:16997): (MLLT11 transcription factor 7 cofactor) The gene variously symbolized ALL1, HRX, or MLL located on 11q23 has been demonstrated to be fused with a number of translocation partners in cases of leukemia. t(1;11)(q21;q23) translocations that fused the MLL gene to a gene on chromosomal band 1q21 in 2 infants with acute myelomonocytic leukemia have been demonstrated. The N-terminal portion of the MLL gene is critical for leukemogenesis in translocations involving band 11q23. This gene encodes 90 amino acids. It was found to be highly expressed in the thymus but not in peripheral lymphoid tissues. In contrast to its restricted distribution in normal hematopoietic tissue, this gene was expressed in all leukemic cell lines tested. [provided by RefSeq, Jul 2008]

CDC42SE1 (HGNC:17719): (CDC42 small effector 1) Predicted to enable GTPase inhibitor activity. Predicted to be involved in signal transduction. Located in cell junction. [provided by Alliance of Genome Resources, Apr 2022]

Collection Method: clinical testing

The c.32C>A (p.S11Y) alteration is located in exon 2 (coding exon 1) of the MLLT11 gene. This alteration results from a C to A substitution at nucleotide position 32, causing the serine (S) at amino acid position 11 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
