First impression

Protocol

Further information can be found in the protocol.

HGMD

74 (79 in 2012 professional) total for cDNA sequence NM_000049.2 and amino acid sequence NP_000040.1, out of which

• 47 missense/nonsense
• 5 splicing
• 12 small deletions
• 2 small insertions
• 1 indel
• 7 gross deletions

SNPdbe

• 55 total, includes predicted functional effect. 29 of these 55 labelled as involved in Canavan Disease.

dbSNP

• same identifiers for sequence as HGMD
• "synonymous-codon"[Function_Class] AND ASPA[GENE] AND "human"[ORGN] AND "snp"[SNP_CLASS] yields only 9 results
• 505 results for SNPs in general in human
  • 458 for NP_000040.1 (coding: 23)
  • 493 for NP_001121557.1 (coding: 23)

Coding SNPs

From the above mentioned SNP databases we extracted all coding SNPs for Aspartoacylase. We used the sequence position of the listed SNPs as identifier to create a unique list of known SNPs. <xr id="coding_snp_table"/> shows the resulting list of unique SNPS. For each polymorphism, the source is given (from which DB the SNP was extracted), as well as annotated validation.
