+Package for data collection purposes provides both collection and refactoring functionality.
+
+Data from LOVD, ClinVar and GnomAd databases can be downloaded using this package. GnomAd and
+ClinVar are limited with EYS gene, but it is possible to download data for any gene in LOVD.
+
+All necessary functionality can be imported directly from data without
+specifying the module.
+
+data collection pipeline example is established for project's specific usage.
