Question

How can databases of variants be used to help pinpoint a disease-causing mutation?

Answer 1

The human gene mutation database (HGMD) is a collection of published germ-line mutations in nuclear genes that underlie , or are closely associated with human inherited disease.

For identifying the pathogenic mutation among thousands to millions of genomic variant is a major challenges and prioritization strategies are required. Current strategies for Mendelian disease gene identification by exome re-sequencing.

Next generation sequencing (NGS) has been  used to identify new pathogenic mutations and genes causing rare genetic diseases.  The analyses of NGS data is not trivial and required a technically and biologically rigorous pipeline that address the data quality , accurate variant filtration to minimize mistakes.
