Conventions for submission and evaluation
Blunt/short joins should be resolved by reference to adequate overlapping
sequence data by one of the following means:
- submission to the database of additional finished overlap data from the
flagged clones or from a new overlapping clone.
- submission of a certificate indicating an overlapping portion of an
unfinished accession that supports the join by overlap.
In general, providing a comment about any fosmid or BAC linking
information is helpful. Excessive numbers of linking clones may be a cause for closer examination.
Questioned polymorphic joins should be resolved by submitting a certificate. For
polymorphic joins, include the size of the polymorphic region (e.g. number of
extra bases due to SSLP, etc.) and its location. For questioned joins due to
SINE, LINE, or SSLP:
- Support by BAC- or fosmid-end linking information in the
certificate is sufficient to validate. No PCR or other analysis need be done unless the coordinator desires to. If there is only a single link, it may be worth erring on the side of caution. If there are multiple distinct problems
of this type in one join, additional analyses should usually be done. If there appear to be excessive BAC or fosmid links, the certificate will be flagged for further discussion.
- If there is no support from BAC or fosmid linking data,
experimental support (e.g. PCR analysis of several individuals) should be obtained (and stated in certificate) to validate.
- For questioned joins due to other types of polymorphisms (in/dels, inversions, etc.), a certificate is valid only if additional support (e.g. PCR) is provided beyond linking information.
General comments:
- The information in the certificate should state why the submittor thinks the join is valid.
- Certificates should include the length of overlap between clones.
- BAC- and fosmid-end linking information is allowable as support and
should be included in certificates.
- Certificates should be submitted for questioned joins even if problems are not yet resolved. Comment should state "not yet resolved".
- If a join has more than one problem, only one certificate should be submitted listing both problems. Generally, the more severe problem should be listed first. If the problems are of two different types (e.g. polymorphism and blunt join), the certificate category should be used for the more serious problem.
Addendums
The evaluator will add the following to all certificates upon examination:
EVALUATION: {word}
REMARK: {text}
with the following allowable "words":
- Pass
- Return (return to coordinator)
- In process (this is for cases clearly being worked on in the right way but
not yet resolved)
- Disputed (for Return cases where there is not agreement after one round of
back-and-forth)
- Unresolved (this is a catch-all for any unresolved situation that
is not in one of the above categories)
