Tandem duplications at 10q24 are associated with split hand/foot malformation 3 (SHFM3) syndrome: PMID: 12913067 De Mollerat (2003): This is a report of 7 patients with SHFM3 (split hand/foot malformation 3) who all had a tandem duplication which included LBX1, BTRC, and POLL, and had a breakpoint within FBXW4 (DAC). PMID: 19584065 Dimitrov (2010): This paper include 6 patients with both syndromic and non-syndromic SHFM3 who have duplications at 10q24 of varying size, which include POLL. They comment on genotype-phenotype correlations. PMID: 16691619 Lyle (2006): Report of 2 families with SHFM3 with minimal 325 kb duplication that includes only BTRC and POLL.
