Clinical Description OMIM |
Shrimal et al. (2013) reported 2 sibs, born of consanguineous Pakistani parents, with a congenital disorder of glycosylation. The patients had delayed psychomotor development with mental retardation, microcephaly, failure to thrive, seizures, hypotonia, and cerebellar atrophy. At age ... |
Molecular genetics OMIM |
In 2 sibs, born of consanguineous Pakistani parents, with congenital disorder of glycosylation type Iw, Shrimal et al. (2013) identified a homozygous missense mutation in the STT3A gene (V626A; 601134.0001). The mutation was found by homozygosity mapping and ... |
