The variant allele was found at a frequency of 0.448 in 151,928 control chromosomes in the GnomAD database, including 15,382 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.45 (15382 hom., cov: 31)
• Consequence: DOT1L NM_032482.3 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.407

Genes affected

DOT1L (HGNC:24948): (DOT1 like histone lysine methyltransferase) The protein encoded by this gene is a histone methyltransferase that methylates lysine-79 of histone H3. It is inactive against free core histones, but shows significant histone methyltransferase activity against nucleosomes. [provided by RefSeq, Aug 2011]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-1.03).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.459 is higher than 0.05.
