Arina Puzriakova (Genomics England Curator)

Green List (high evidence)

Comment on list classification: With the addition of the recent publication, there are now at least three unrelated cases reported with a renal phenotype, and therefore enough evidence for a rating upgrade from Amber to GREEN at the next major review.

Associated with phenotype in OMIM and a possible gene for Bardet-Biedl syndrome 19 in G2P.

Sanchez-Navarro et al. (2018) (PMID: 29588463) report the two compound heterozygous variants (c.104A>G and c.350-2A>G), in a BBS patient with chronic renal failure, albeit no segregation or functional studies were undertaken.

Eleanor Williams (Genomics England Curator)

PMID: 30761183 - Schaefer et al 2019 - two compound heterozygous mutations in IFT27 identified by WES in a child presenting with the classical BBS signs. However, NO renal phenotype was found.

As this is not a third case with a renal phenotype this gene should stay amber on this panel.

Bardet-Biedl syndrome 19, MIM# 615996


Rebecca Foulger (Genomics England curator)

Comment on list classification: Updated rating from Red to Amber based on presence of second paper: PMID:29704304 (2018) with ciliopathy phenotype, and added 'watchlist' tag.

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.
