I just came across the [ENSEMBL ](https://useast.ensembl.org/info/about/index.html)database which has [Python API](https://bioinformatics.stackexchange.com/questions/4827/python-api-for-working-with-ensembl-genomes) and seems to have few or no access restrictions. It has [NF1](https://useast.ensembl.org/Homo_sapiens/Gene/Summary?db=core;g=ENSG00000196712;r=17:31094927-31382116) and lots of structural information (gene expression, pathways, regulation, orthologues, paralogues and so on).
