Genes affected

ASH1L (HGNC:19088): (ASH1 like histone lysine methyltransferase) This gene encodes a member of the trithorax group of transcriptional activators. The protein contains four AT hooks, a SET domain, a PHD-finger motif, and a bromodomain. It is localized to many small speckles in the nucleus, and also to cell-cell tight junctions.

The c.8487G>T (p.Lys2829Asn) variant substitutes a completely conserved Lysine for Asparagine at amino acid 2829/2965 (coding exon 26/28).This variant is found with low frequency in gnomAD (5 heterozygotes, 0 homozygotes; allele frequency: 1.99e-5) and ExAC (2 heterozygotes, 0 homozygotes; allele frequency: 1.65e-5), suggesting it is not a common benign variant in the populations represented in these databases. In silico algorithms do not agree on the effect of this variant, as it is predicted Neutral (Provean; score: -2.13) and Damaging (SIFT; score: 0.001) to the function of the canonical transcript. To our current knowledge has not been reported in affected individuals in the literature. The p.Lys2829 residue does not map to a specific domain and is C-terminal to the highly conserved BAH domain. -
