Variant summary

Our verdict is Benign. The variant received -8 ACMG points: 0P and 8B. BP4_StrongBS2

The NM_001195626.3(MLLT10):​c.823A>G​(p.Ile275Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000112 in 1,613,818 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. I275M) has been classified as Uncertain significance.

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]

The c.823A>G (p.I275V) alteration is located in exon 9 (coding exon 9) of the MLLT10 gene. This alteration results from a A to G substitution at nucleotide position 823, causing the isoleucine (I) at amino acid position 275 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
