Genetic diseases of connective tissue: Williams syndrome. PI: Victoria Campuzano Uceda

Presentation

Williams-Beuren syndrome (WBS) [OMIM 194050] is a neurodevelopmental disorder caused by the heterozygous deletion of 26-28 contiguous genes on chromosome 7q11.23 that affects 1/7500-1/20000 newborns. WBS individuals present mild to moderate intellectual disability, with a mean intelligence quotient (IQ) of 55-60. The syndrome is characterized by a unique cognitive functioning including relatively preserved expressive language and facial processing abilities along with hypersociability towards strangers but dramatic deficits in spatial cognition. Mainly due to Elastin (ELN) deficiency, WBS patients show a generalized arteriopathy characterized by hypertrophy of smooth muscle cells, increased number and disorganized lamellar structures, and fragmented elastic fibers. The complete deletion (CD) mouse model captures several behavioral and cardiovascular defects that are seen in humans with WBS.

  • Identification of molecular biomarkers: Analyze mitochondrial function in tissues (and cells derived from them) mainly affected in the CD mouse model (cardiac and neural).
  • Identification of the major player in mitochondria dysfunction: genetic rescue of DNAJC30 gene expression in cell cultures derived from the CD model.
  • Analysis of a possible depressive behaviour: Behavioral characterization of CD mouse model in relationship with the depressive phenotype.
  • Identification of “in vivo” cardiovascular biomarquers: Electrocardiogram to CD animals
  • Genetic rescue by means of Adeno-associates of the expression of the DNAJC30 gene
  • Pharmacological intervention: combining anti-hypertensives and mitochondria-targeted therapies

  • Studying the mitochondrial health of cardiomyocytes and vascular smooth muscle cells in Williams Syndrome
