Genes affected

MLLT3 (HGNC:7136): (MLLT3 super elongation complex subunit) Enables chromatin binding activity and lysine-acetylated histone binding activity. Involved in several processes, including hematopoietic stem cell differentiation; positive regulation of transcription, DNA-templated; and regulation of stem cell division. Acts upstream of or within negative regulation of canonical Wnt signaling pathway and positive regulation of Wnt signaling pathway, planar cell polarity pathway. Located in cytosol and nucleoplasm. Part of transcription elongation factor complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.1321C>G (p.R441G) alteration is located in exon 7 (coding exon 7) of the MLLT3 gene. This alteration results from a C to G substitution at nucleotide position 1321, causing the arginine (R) at amino acid position 441 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
