Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_001043229.2(CSKMT):​c.268T>A​(p.Cys90Ser) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 14/21 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. C90R) has been classified as Uncertain significance.

Genes affected

CSKMT (HGNC:33113): (citrate synthase lysine methyltransferase) Enables protein-lysine N-methyltransferase activity. Involved in peptidyl-lysine dimethylation; peptidyl-lysine monomethylation; and peptidyl-lysine trimethylation. Predicted to be located in mitochondrion.

LBHD1 (HGNC:28351): (LBH domain containing 1) This gene shares three exons in common with another gene, chromosome 11 open reading frame 98 (GeneID:102288414), but the encoded protein uses a reading frame that is different from that of the chromosome 11 open reading frame 98 gene.

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.09075591).
