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. [provided by Alliance of Genome Resources, Apr 2022]
LAMTOR4 (HGNC:33772): (late endosomal/lysosomal adaptor, MAPK and MTOR activator 4) Contributes to guanyl-nucleotide exchange factor activity and molecular adaptor activity. Involved in several processes, including cellular response to amino acid stimulus; positive regulation of TOR signaling; and protein localization to lysosome. Located in lysosome. Part of Ragulator complex. [provided by Alliance of Genome Resources, Apr 2022]
