RCV000128641 | SCV004223600 | pathogenic | Bardet-Biedl syndrome 19 | 2023-11-09 | criteria provided, single submitter | clinical testing | Variant summary: IFT27 c.296G>A (p.Cys99Tyr) results in a non-conservative amino acid change located in the Small GTP-binding protein domain (IPR005225) of the encoded protein sequence. Five of five in-silico tools predict a damaging effect of the variant on protein function. The variant was absent in 251490 control chromosomes. c.296G>A has been reported in the literature as a biallelic homozygous genotype in at-least two individuals from one consanguineous family affected with Bardet-Biedl Syndrome 19 (example, Aldamesh_2014 cited by Shaheen_2016, Zhou_2022, Schaefer_2019). It has also been observed as a homozygous occurrence in an internal case affected with features of Bardet-Biedl Syndrome. These data indicate that the variant is very likely to be associated with disease. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. The following publications have been ascertained in the context of this evaluation (PMID: 24488770, 30761183, 27894351, 34888642). No submitters have cited clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as pathogenic. |
