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]

The c.329C>T (p.A110V) alteration is located in exon 2 (coding exon 1) of the TAL1 gene. This alteration results from a C to T substitution at nucleotide position 329, causing the alanine (A) at amino acid position 110 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
