Genes affected
TRAPPC14 (HGNC:25604): (trafficking protein particle complex subunit 14) Enables alpha-tubulin binding activity. Involved in cilium assembly and regulation of cell population proliferation. Located in several cellular components, including microtubule cytoskeleton; midbody; and plasma membrane. Part of TRAPPII protein complex. Implicated in primary autosomal recessive microcephaly.
