Description

The IFT27 c.473delA variant is predicted to result in a frameshift and premature protein termination (p.Asn158Thrfs*51). To our knowledge, this variant has not been reported in the literature or in a large population database, indicating this variant is rare. Only a few truncating variants in this gene have been reported in individuals with Bardet-Biedl syndrome in the Human Gene Mutation Database and in ClinVar. Although we suspect that this variant may be pathogenic, at this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence.
