Biochemical Genetics Department, Cyprus Institute of Neurology and Genetics RCV001725923 SCV001950177 pathogenic Deficiency of UDPglucose-hexose-1-phosphate uridylyltransferase criteria provided, single submitter clinical testing This deletion eliminates all GALT exons as well as the non-translated sequences of the adjacent interleukin 11 receptor alpha (IL11RA) gene causing classic galactosemia with additional phenotypic abnormalities such as craniosynostosis (Papachristoforou et al., 2014). Similar deletions of the entire GALT sequence have been also reported in individuals affected with galactosemia (Berry et al., 2001; Bosch et al., 2005; Coffee et al., 2006). Previous reports implicate mutations in the IL11RA gene as being responsible for craniosynostosis (Coussens et al., 2008; Nieminen et al., 2011).The RNA expression studies showed lack of IL11RA transcripts in the patients. These findings strongly suggest that the new deletion simultaneously eliminates GALT and IL11RA expression (contiguous deletion) and for these reasons, this variant meets our criteria to be classified as Pathogenic.
