Genes affected

TAL1 (HGNC:11556): (TAL bHLH transcription factor 1, erythroid differentiation factor) Enables several functions, including DNA-binding transcription factor activity; E-box binding activity; and histone deacetylase binding activity. Involved in several processes, including myeloid cell differentiation; positive regulation of cellular component organization; and positive regulation of erythrocyte differentiation. Located in chromatin and nucleoplasm. Part of transcription regulator complex. Implicated in acute lymphoblastic leukemia. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Sep 26, 2022

The c.805G>A (p.G269S) alteration is located in exon 4 (coding exon 3) of the TAL1 gene. This alteration results from a G to A substitution at nucleotide position 805, causing the glycine (G) at amino acid position 269 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
