What is the normal function of the TULP1 gene?
- From NCBI Gene:
This gene encodes a member of the tubby-like gene family (TULPs). Members of this family have been identified in plants, vertebrates, and invertebrates and encode proteins of unknown function. TULP proteins share a conserved C-terminal region of approximately 200 amino acid residues. Mutations in this gene may be associated with juvenile retinitis pigmentosa and Leber congenital amaurosis-15. Alternative splicing results in multiple transcript variants.

- From UniProt:
Required for normal development of photoreceptor synapses. Required for normal photoreceptor function and for long-term survival of photoreceptor cells. Interacts with cytoskeleton proteins and may play a role in protein transport in photoreceptor cells (By similarity). Binds lipids, especially phosphatidylinositol 3-phosphate, phosphatidylinositol 4-phosphate, phosphatidylinositol 5-phosphate, phosphatidylinositol 3,4-bisphosphate, phosphatidylinositol 4,5-bisphosphate, phosphatidylinositol 3,4,5-bisphosphate, phosphatidylserine and phosphatidic acid (in vitro). Contribute to stimulation of phagocytosis of apoptotic retinal pigment epithelium (RPE) cells and macrophages.
How are changes in the TULP1 gene related to health conditions?
- Genetics Home Reference provides information about these conditions associated with changes in the TULP1 gene:
- UniProt provides the following information about the TULP1 gene's known or predicted involvement in human disease.
Retinitis pigmentosa 14 (RP14): A retinal dystrophy belonging to the group of pigmentary retinopathies. Retinitis pigmentosa is characterized by retinal pigment deposits visible on fundus examination and primary loss of rod photoreceptor cells followed by secondary loss of cone photoreceptors. Patients typically have night vision blindness and loss of midperipheral visual field. As their condition progresses, they lose their far peripheral visual field and eventually central vision as well. The disease is caused by mutations affecting the gene represented in this entry.
Leber congenital amaurosis 15 (LCA15): A severe dystrophy of the retina, typically becoming evident in the first years of life. Visual function is usually poor and often accompanied by nystagmus, sluggish or near-absent pupillary responses, photophobia, high hyperopia and keratoconus. The disease is caused by mutations affecting the gene represented in this entry.
- NCBI Gene lists the following diseases or traits (phenotypes) known or believed to be associated with changes in the TULP1 gene.
- Leber congenital amaurosis 15
- Retinitis pigmentosa 14
- OMIM.org, a catalog designed for genetics professionals and researchers, provides the following information about the TULP1 gene and its association with health conditions.
