Summaries for Microcephaly 15, Primary, Autosomal Recessive

UniProtKB/Swiss-Prot : 76 Microcephaly 15, primary, autosomal recessive: A form of microcephaly, a disease defined as a head circumference more than 3 standard deviations below the age, sex and ethnically matched mean. Brain weight is markedly reduced and the cerebral cortex is disproportionately small.

MalaCards based summary : Microcephaly 15, Primary, Autosomal Recessive, is also known as primary autosomal recessive microcephaly 15. An important gene associated with Microcephaly 15, Primary, Autosomal Recessive is MFSD2A (Major Facilitator Superfamily Domain Containing 2A). Affiliated tissues include brain and cortex, and related phenotypes are seizures and hyperreflexia

Disease Ontology : 12 A primary autosomal recessive microcephaly that has material basis in homozygous or compound heterozygous mutation in the MFSD2A gene on chromosome 1p34.
