I'm analysing NGS data from patients and I'm looking for novel pathogenic variants (SNV and indels). After taking a look of the genes present in OMIM and no finding anything relevant, I'm analysing the poorly known genes. Is there any database specialized in poorly characterized or known genes in order to gather information about their function and basic data?

GeneCards (https://www.genecards.org/) works fine but maybe there are better options.
