Abhydrolase Domain Containing Protein 11 (ABHD11)

ABHD11 encodes a protein containing an alpha/beta hydrolase fold domain. This gene is deleted in Williams syndrome, a multisystem developmental disorder caused by the deletion of contiguous genes at 7q11.23. Alternatively spliced transcript variants have been described, but their biological validity has not been determined.

Williams-Beuren syndrome (WBS) is a developmental disorder associated with haploinsufficiency of multiple genes at 7q11.23 They encode an RCC1-like G-exchanging factor, an N-acetylgalactosaminyltransferase, a DNAJ-like chaperone, NOL1/NOP2/sun domain-containing proteins, a methyltransferase, or proteins with no known homologies. Haploinsufficiency of these newly identified WBSCR genes may contribute to certain of the WBS phenotypical features.
