Genes affected
MLLT6 (HGNC:7138): (MLLT6, PHD finger containing) Enables histone binding activity and nucleosome binding activity. Predicted to be involved in positive regulation of transcription by RNA polymerase II. Predicted to act upstream of or within several processes, including negative regulation of histone H3-K79 methylation; renal potassium excretion; and renal sodium excretion. Predicted to be active in nucleus. [provided by Alliance of Genome Resources, Apr 2022]

The c.857C>A (p.A286D) alteration is located in exon 9 (coding exon 9) of the MLLT6 gene. This alteration results from a C to A substitution at nucleotide position 857, causing the alanine (A) at amino acid position 286 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
