#ASHG21 BMG: Bailey Martin-Giacalone.
Germline variants in cancer predisposition genes predict survival for children with rhabdomyosarcoma (RMS) #ASHG21 BMG: RMS most common soft tissue cancer of childhood. Usually two subtypes. alveolar RMS (ARMS) ~80% have a PAX3/7-FOX01 fusion. Embryonal RMS (ERMS) have heterogeneous somatic mutation landscape.

#ASHG21 AN: Aparna Nathan.
Modeling eQTLs at single-cell resolution identifies 2000 eQTLs with differential effects across continuous T cell states. #ASHG21 AN: cell-state dependent eQTLs means that the same genetic variant may have an effect or no effect depending on cell type and activation. How do you find state-dependent QTLs?

#ASHG21 AT: Adelaide Tovar.
A modular massively parallel reporter assay uncovers context-specific allelic activity of GWAS variants. #ASHG21 AT: GWAS hits often not in coding sequence [though plenty are in gene bodies] and suggests that the promoter / enhancer / other non-coding sites may affect gene regulation and therefore disease risk.

#ASHG21 ML: Mischa Lundberg.
Integrative analysis of human genetic association studies, single cell transcriptomics, and knockout mouse models identifies cell types and genes involved in skeletal disease. #ASHG21 ML: Lack of 'omics data for skeletal disorders. Use murine 'omics to try and fill this gap since the data aren't always available for human samples.

#ASHG21 BJS: Benjamin J Strober.
Uncovering context-specific genetic regulation of gene expression from single-cell RNA-sequencing using latent-factor models. #ASHG21 BJS: Many contexts modulate gene expression. Such as cell type, developmental stage, environmental stimulus.
One way to study is to look at eQTLs. Especially context-specific eQTLs. Example might be an eQTL in B cells that isn't an eQTL in T cells.
