A Case of Rafiq Syndrome (MAN1B1-CDG) in a Palestinian Child, With Brief Literature Review of 44 Cases

Rafiq syndrome, MAN1B1-CDG, was described in 2010 and associated with genetic mutation in MAN1B1 gene in 2011. The disorder follows an autosomal recessive pattern of inheritance and typically presents with specific facial dysmorphism, intellectual disability, developmental delay, obesity, and hypoto...

description Rafiq syndrome, MAN1B1-CDG, was described in 2010 and associated with genetic mutation in MAN1B1 gene in 2011. The disorder follows an autosomal recessive pattern of inheritance and typically presents with specific facial dysmorphism, intellectual disability, developmental delay, obesity, and hypotonia. The syndrome belongs to a group of metabolic disorders called Congenital Glycosylation Disorders (CGD). In this study, we discuss a 5-year-old male from Palestine who presented with developmental delay, hypotonia, characteristic facial dysmorphisms, impulsive behaviors, inability to speak, cryptorchidism, and other manifestations. This constellation of manifestations raised suspicion of a genetic disorder, prompting whole exome sequencing (WES), which revealed the presence of a homozygous likely pathogenic variant in the MAN1B1 gene (c.1976T>G)(p.Phe659Cys). We also reviewed all previously documented cases and compared the clinical features among them. After reviewing the family pedigree and its suspected cases, we found that the 2 most frequent features among them are intellectual disability and facial dysmorphism, whereas the least frequent one is truncal obesity. We discussed the importance of providing genetic counseling to parents of children with this and other rare, autosomal recessive disorders to prevent new cases from appearing.
