Genetic Variant MLLT6:p.Ala286Val (chr17-38715649-C-T) – ACMG Classification: Likely_benign (-6 pts)

Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_005937.4(MLLT6):c.857C>T(p.Ala286Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000411 in 1,461,532 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 13/19 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A286D) has been classified as Uncertain significance.

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]
