Genes affected

MLLT10 (HGNC:16063): (MLLT10 histone lysine methyltransferase DOT1L cofactor) This gene encodes a transcription factor and has been identified as a partner gene involved in several chromosomal rearrangements resulting in various leukemias. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Sep 2010]

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.861

The c.455G>C (p.G152A) alteration is located in exon 5 (coding exon 5) of the MLLT10 gene. This alteration results from a G to C substitution at nucleotide position 455, causing the glycine (G) at amino acid position 152 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
