Researching SNPs Gaucher Disease

The aim of this task was to map non-synonymous SNPs known for the Gaucher Disease causing gene GBA onto the corresponding protein sequence P04062. Several databases should be taken into account, namely HGMD<ref name="hgmd">Stenson et al. (2009). The Human Gene Mutation Database (HGMD): 2008 Update. Genome Med</ref>, dbSNP<ref name="dbsnp">Sherry ST, Ward M, and Sirotkin, K. (1999). dbSNP - database for single nucleotide polymorphisms and other classes of minor genetic variation.

HGMD

The Human Genome Mutation Database (HGMD) is a collection of observed mutations in the human genome which are associated with various diseases. The mutations are taken from publications, both manually and automatically [1]. There is a public version with 88745 entries (9th June, 2012) and a professional version with 123565 entries. Since 2009, the public version has been extended only by few new entries such that it does no longer contain all currently known mutations [2]. The HGMD encompasses following types of mutations:

Missense

Mutations which result in another amino acid

Nonsense

Mutations which result in a stop codon

Splicing

Mutations which alter splice sites

Regulatory

Mutation which alter gene regulation

Small/gross deletions

Deletions which remove residues

Small/gross insertions

Insertions which give rise to new residues

Small indels

Insertions or deletions

Duplications

Duplication of gene fragments

Complex rearrangements

Change in the location for gene fragments

Repeat variations

Varying number of sequence copies

<xr id="tab:hgmd_number"/> lists the number of mutations annotated in HGMD for GBA. A comprehensive list of all missense/nonsense mutations can be obtained by following the respective hyperlink.

<figtable id="tab:hgmd_number">

<xr id="tab:hgmd_map"/> shows the wildtype version of P04062 with non-synonymous mutations highlighted in red. Since the transcript NM_001005741.1 already referred to P04062, the amino acid positions could be used directly for creating <xr id="tab:hgmd_map"/> without any additional translation.

<figure id="fig:hgmd_2nt0_A">

Genetic variants of P04062 annotated in HGMD mapped to 2nt0_A. Red: non-synonymous mutations

</figure>

In order to get an expression about the structural elements which are subject to mutations, we mapped the mutations of <xr id="tab:hgmd_map"/> from P04062 to its closest crystal structure 2nt0. We found that the mutations were scattered all over the structure without major aggregations in certain domains (cf. <xr id="fig:hgmd_2nt0_A"/>).

dbSNP

dbSNP is a publicly available collection of genetic variations from different species. Genetic variations include (1) SNPs, (2) short deletion and insertion polymorphisms (indels/DIPs), (3) microsatellite markers or short tandem repeats (STRs), (4) multinucleotide polymorphisms (MNPs), (5) heterozygous sequences, and (6) named variants. Genetic variants are submitted by, amongst others, research institutions, large scale genome sequencing centers, and other SNP databases. Statistics about the latest release can be found here.

Variations of GBA in dbSNP included 92 missense mutations, 47 synonymous mutations and 3 deletions. Missense and synonymous mutations are visualized in <xr id="tab:dbsnp_map"/>. All three deletions cause a frame-shift due to the loss of a single nucleotide which severely alters the amino acid sequence after the position where the mutation occurred. The effect would be less severe if a complete codon were inserted or deleted which would change the length of the protein sequence but not the amino acid composition.

SNPdbe

SNPdbe (nsSNP database of functional effects) is a database and a web interface which provides predictions of computationally annotated functional impacts of SNPs. Instead of SNPs, each entry is represented as a SAAS (single amino acid substitution) which means each non-synonymous SNP (nsSNP) changes one amino acid in the gene product. The impact of SAAS is predicted by using the SNAP and SIFT algorithms and is augmented with the information and disease associations from PMD, OMIM and UniProt. In the up to date version (2012/03/05), SNPdbe contains 1691464 entries/SAASs which belong to 2985 Organisms and 159142 Protein sequences.

We tried to search the gene symbol(GBA), protein (UniProt) id(P04062), and the disease name (gaucher), different number of SNPs were returned (GBA: 563, p04062: 163, gaucher: 174). The results were all mixed with the SAASs located at similar protein sequences from different database (e.g. NCBI or UniProt).

The searching results which were only limited to the protein seqeunce p04062 returns 65 SAASs, in red color as showing in the following map. All of them have no experimental evidence. The SAASs with high conservation score (which showed that is a mutant more than a wildtype) are labeled in blue :

OMIM

OMIM (Online Mendelian Inheritance in Man) is a database containing information on all known genetic disorders and the corresponding genes in human genome with particular focus on the molecular relationship between phenotype and genotype. In the up to date version (8 June 2012), there are 19971 autosomal related, 1171 X-linked,59 Y-linked, 65 Mitochondrial related entries. Each entry is either Gene description with/without phenotype information, or phenotype description with/without molecular basis.

Searching OMIM againt "GBA" returned 27 entries. 7 of them are clearly related to Caucher disease.The others are related to Parkinson disease, Prostate cancer etc. Among them *606463 is the most representative one which contains 48 variants. The most of them have links to dbSNP. In OMIM, abundant scientific publications are given for each entry which provide confirmed evidence for annotation/validation purpose.

SNPedia

SNPedia is wiki styled database providing the information about the effects of SNPs. Each entry contains a description of a SNP, together with the links to scientific publications and other related genomics web sites. The SNPs data is supported by some personal genomics company, e.g., 23andMe, Navigenics, deCODEme or Knome. In the up to data version of SNPedia, there are 29135 SNPs.

There is one entry for gene "GBA" and one entry for "Gaucher Disease" respectively. Both list only the most important SNPs which were experimentally confirmed to be strongly associated to gaucher disease, e.g.N370S,L444P,D409H etc.

Mutation map

In the following mapping, SNPs(only synonymous) from different data sources (HGMD,dbSNP, SNPdbe) are shown. We can see that the SNPs data from different database varied. It might suggest that the most SNPs (even though they are missense) are evolutionary neutral and therefore lead to no obvious impact on the function of its gene product. <xr id="fig:compare"/> is a representation of PDB structure with annotated/predicted SNPs from different databases. The residues in purple are the SNPs found in at least two different databases. The residues in red are unique SNPs from HGMD. The residues in green are unique SNPs from dbSNP and the residues in blue are unique SNPs from SNPdbe. <xr id="fig:venn_compare"/> shows the intersection and unique part of SNPs from different databases. We can see that overall 200 SNPs (only synonymous) are reported from HGMD,dbSNP and SNPdbe. HGMD has return the most part of SNPs and SNPdbe the least. Only 20 SNPs are reported by all three databases, therefroe deserve further investigation.
