Phenotype of ST3GAL3 deficient patients: A case and review of the literature

Hossein Jafari Khamirani et al. Eur J Med Genet. 2021 Aug.

Abstract

ST3GAL3 deficiency is an extremely rare autosomal recessive disorder caused by pathogenic mutations in the ST3GAL3 gene. Epilepsy, motor development delay, severe intellectual disability, and behavioral disorders have been reported to be associated with ST3GAL3 deficiency. In the present study, ST3GAL3 deficiency was caused by a homozygous splice-site mutation (NM_174964.4: c.936+1delG) in ST3GAL3. The patient described in this study was clinically similar to previously reported cases; nevertheless, we were able to detect repetitive behavior, previously not reported manifestations.

Keywords: Intellectual disability; Motor disorders; ST3GAL3; ST3GAL3 deficiency; Whole-exome sequencing.
