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]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2024The c.821G>A (p.G274D) 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 821, causing the glycine (G) at amino acid position 274 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
