Critical failures (undesignable)
101= Flanking sequence is too short.
102= SNP or sequence formatting error. SNP must match the format:[X/Y]
Possible causes:
- Spaces found in submitted sequence.
- More than one set of brackets in sequence. Missing brackets around SNP
- SNP alleles not separated by a ¡°/¡±
103=Top/Bot strand cannot be determined. Low sequence complexity
104=SNP is not appropriate for Illumina platform.
Possible causes:
- Tri- or quad-allelic SNP
- Insertion or deletion polymorphism
- SNP contains characters other than A, G, C, or T
106=Degenerate nucleotide(s) in assay design region
- e.g. W, R, S, N, etc.

Warnings (designable)
301=SNP in duplicated/repetitive region
302=Tm outside assay limits
340=Another SNP in this list is equal to or less than 60 nucleotides away.
399= Multiple contributing issues
