From NCBI Gene:

This gene encodes a large protein whose specific function is unknown. Absence of the orthologous protein in mouse results in embryonic lethality with deficient axial rotation, abnormal differentiation of the neural tube, and randomized looping of the heart tube during development. In human, mutations in this gene are associated with polymicrogyria with seizures. In human fibroblasts this protein localizes at the ciliary basal bodies. Given the intracellular localization of this protein and the phenotypic effects of mutations, this gene is suspected of playing a role in the maintenance of normal ciliary structure which in turn effects the developmental process of left-right organ specification, axial rotation, and perhaps notochord development.

From UniProt:

Involved in the genetic cascade that governs left-right specification. Plays a role in the maintenance of a normal ciliary structure. Required for correct asymmetric expression of NODAL, LEFTY and PITX2.

  • Microcephaly, short stature, and polymicrogyria with or without seizures

From UniProt:

Microcephaly, short stature, and polymicrogyria with or without seizures (MSSP): A disease characterized by many irregular small gyri in the brain surface and fusion of the molecular layer over multiple small gyri, which gives a festooned appearance to the cortical surface, without abnormal neuronal migration. Polymicrogyria is a heterogeneous disorder, considered to be the result of postmigratory abnormal cortical organization. MSSP patients have moderate to severe mental retardation, poor speech, dysarthria and seizures. [MIM:614833]
