Researching SNPs (PKU)

Short Task Description

In this weeks task, we will research SNPs in the PAH gene that cause or do not cause a different phenotype of the phenylalanine hydroxylase. The chosen databases are: The public release of the Human Gene Mutation Database (HGMD), dbSNP, SNPdbe, OMIM and SNPedia. You may find a detailed task description here.

Databases

Overview

<figtable id="tab:modelling_scores"> Key Values of the different SNP databases

Database	Last Update	Number of Entries	Number of Entries concerning PAH	Type of information	Sources	Curation/Verification	Comment
HGMD	public after 3 years (quarterly updated)	50,129 (only mis-/nonsense)	397 (only mis-/nonsense)	all types of mutations	current literature	manual and computerised search in current literature	too much advertising
dbSNP	Oct 2011	292,031,791	2590	SNPs, short in/dels, polymorphisms, others	submitted by registered sources (labs, institutes,.. )	clustering of identical submissions by NCBI
SNPdbe	Mar 2012	1,691,464	328	nonsyn. SNPs	Swissprot, dbSNP, PMD, OMIM, 1000 genomes	cf. sources	Predictions of functional effect, experimental evidence if available in source
OMIM	June 2012	21,257 (Summary entries)	1 (64 selected SNPs)	catalog of human genes and genetic disorders and traits	current literature	manually curated
SNPedia	continuous, Wiki-style	29,058	53	SNPs	publicly edited	publicly edited	get genotyped and predicted
