Aldahmesh et al. (2014, PMID:24488770) identified a homozygous c.296G-A transition in the IFT27 gene (p.C99Y) in a consanguineous family with two affected children with Bardet-Biedl syndrome-19 (MIM:615996). Additional signs in one sibling included polydactyly.

PMID:29704304 (2018) describe a fetus with an unclassified severe ciliopathy phenotype including short ribs, polydactyly, bilateral renal agenesis, and imperforate anus, with compound heterozygosity for c.118_125del, p.(Thr40Glyfs*11) and a c.352 +1G>T in IFT27.
