^aNumber of markers.
^b Number of distinct positions.
^c Number of markers with homologous human sequence, determined by BLAT alignments between marker sequences and UCSC hg17 sequence..
^d Mean interval between distinct positions.
^e Maximum interval between distinct positions.
^f Coefficient of variation for marker spacing. Low values indicate relatively even space between markers; high values indicate uneven spacing with clusters of markers separated by gaps.
^g Newly developed and mapped EST- and BAC-based SNP.
^h All other markers, including markers from previously described maps and newly mapped markers with data contributed by other projects.
