\colorBlock{Background}{Introduction}{1}{
Unambiguous and correct sequence variant descriptions are of utmost
importance for DNA diagnostics. The free Mutalyzer sequence variation
nomenclature checker
(\color{red}\bt{http://www.mutalyzer.nl/}\color{LUMCBlue}) names variants
importance for DNA diagnostics. Descriptions can be checked and corrected
with the {\em Mutalyzer sequence variation nomenclature checker}
(Fig.~\ref{figure:namecheck}) (\color{red}\bt{http://www.mutalyzer.nl/}\color{LUMCBlue})
following the Human Genome Variation Society (HGVS) sequence variant
nomenclature recommendations~\cite{HGVS}.

\colorBlock{WhiteBg}{Conclusions}{1}{
Variants at intergenic, exonic, intronic, CDS and UTR positions can be
easily distinguished based on their gene-centered HGVS descriptions.
Mutalyzer facilitates batch-wise conversion from dbSNP rsIDs or
chromosomal position numbering of next generation sequencing data to
transcript position numbering, as well as sequence variant checking of
locus-specific sequence variant databases (LSDBs)~\cite{LOVD}.
Initial construction of variant descriptions, however, requires comparison
of the reference sequence and the variant sequence and basic knowledge of
the HGVS recommendations. With the arrival of long read sequencers (e.g.
PacBio) and the rise of sophisticated variant callers, the chance of
finding a complex variant increases and so does the need to describe these
variants.
