      PMID: 30839500

      Gene: BBS7

      HGNC: 18758

      Disease: Bardet-Biedl syndrome 7

      MONDO: 0014435

      InheritancePattern: autosomal recessive

      Prevalence: The prevalence of BBS7 variants among Bardet-Biedl syndrome cohorts has been reported at 4.2% (PMID: 19402160), while the prevalence of Bardet-Biedl syndrome overall has been estimated between 1 in 13,500 and 1 in 160,000 live births, depending on the population (PMID: 22713813).

      Gene: IFT140

      HGNC: 29077

      Disease: Short-rib thoracic dysplasia 9 with or without polydactyly

      MONDO: 0009964

      InheritancePattern: autosomal recessive

      Prevalence: Within the lumped disease entity for this curation, the most prevalent form may be retinitis pigmentosa. The prevalence of Saldino-Mainzer syndrome (one of the synonyms of Short-rib thoracic dysplasia 9) is less than 1 in 1,000,000. The prevalence of Leber congenital amaurosis cases caused by IFT140 variants (PMID: 26216056) is calculated to be less than 1 in 3,000,000. Although IFT140 variants are estimated to be responsible for less than 2% of RP, the prevalence of the overall disorder at 1 in 3,000 or 1 in 4,000 means the frequency of these cases could potentially be higher than 1 in 1,000,000.

      Penetrance: Known variants for this lumped disease entity appear to be completely penetrant, with highly variable phenotypes and age of onset. On the other hand, the split disease entity caused by monoallelic IFT140 variants appears to have incomplete penetrance.

      Direct gene sequencing of β-myosin heavy chain (MYH7), myosin binding protein-C (MYBPC3), and cardiac troponin T (TNNT2) was performed in 136 unrelated Chinese HC patients. Clinical evaluations were conducted. In total, 32 mutations were identified in 36 patients (27%), including 10 novel ones. Distribution of mutations was 56% (MYBPC3), 31% (MYH7), and 13% (TNNT2), respectively. Double mutations were identified in 3% patients.

      HGNC: 7577

      "This is the first indication that a mutation in the MYH7B gene causes LVNC cardiomyopathy. We demonstrated that the arginine at position 890 of the MYH7B gene is highly conserved in all species; this region is also conserved in the MYH7 gene, which, when mutated, causes LVNC. These data further support the concept that sarcomere genes are associated with LVNC."
