Description

By whole-exome sequencing in a 4-year-old boy (patient 2), born to consanguineous Iranian parents, with neurodevelopmental disorder with progressive microcephaly, spasticity, and brain imaging abnormalities (NEDMISBA; 616486), Scala et al. (2020) identified a homozygous c.556+1G-A mutation (c.556+1G-A, NM_032793.5) in the MFSD2A gene, predicted to result in aberrant splicing through alteration of the splice donor site. The mutation segregated with the disorder in the family and was not present in homozygosity in public variant databases, including gnomAD.
