Notes:
3. For the most part, a length of 6 characters suffices for syndrome abbreviations.
Another opportunity for a standard and alphabetic/logographic awareness. 
4. among the gene types currently in use are unknown, protein-coding, trisomy,
non-protein-coding, transposon, pseudo-gene,  and non-functional.
5. among the mutation types are mosaic, trans-location; deletion, single nucleotide
change; several types of nucleotide repeats and other. There is no description for
epigenetic variations yet.
6. these take the form of either a location or a range
[a] 'm' for mitochondria with an offset required
[b] p or q (short versus long arm) followed by up to five characters of the form nn.nn
[c] p or q as above followed by up to five characters as above plus space dash space
followed by nn.nn
note that for a jumped gene or a transposon this will describe where the gene is as
opposed to where it is supposed to be.
7. this is the length in nucleotides of the mutation - it would be a positive integer for
repeats and a negative integer for deletes. How well this will describe conditions such as
mosaic rings remains to be seen
