The conversion chart at Ysearch can be helpful, except that it is sometimes out of date. It doesn't include mention of GenBase: http://www.ysearch.org/conversion_page.asp The best place to compare standards is usually the page at SMGF, although the chart only includes the markers tested by SMGF: http://www.smgf.org/ychromosome/marker_standards.jspx Beyond that, I have no answer to your question.
