Genes affected

TLX1 (HGNC:5056): (T cell leukemia homeobox 1) This gene encodes a nuclear transcription factor that belongs to the NK-linked or NK-like (NKL) subfamily of homeobox genes. The encoded protein is required for normal development of the spleen during embryogenesis. This protein is also involved in specification of neuronal cell fates. Ectopic expression of this gene due to chromosomal translocations is associated with certain T-cell acute lymphoblastic leukemias. Alternate splicing results in multiple transcript variants.

The c.190G>A (p.A64T) alteration is located in exon 1 (coding exon 1) of the TLX1 gene. This alteration results from a G to A substitution at nucleotide position 190, causing the alanine (A) at amino acid position 64 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
