HYLS1 gene

HYLS1, centriolar and ciliogenesis associated

From NCBI Gene:

This gene encodes a protein localized to the cytoplasm. Mutations in this gene are associated with hydrolethalus syndrome. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Oct 2008]

From UniProt:

Plays a role in ciliogenesis.

From NCBI Gene:

  • Hydrolethalus syndrome 1

From UniProt:

Defects in HYLS1 may be involved in ciliopathies other than hydrolethalus syndrome 1. A homozygous mutation resulting in a C-terminal extension of 11 residues has been found in patients diagnosed as Joubert syndrome, a ciliopathy presenting with cerebellar ataxia, oculomotor apraxia, hypotonia, neonatal breathing abnormalities and psychomotor delay. Neuroradiologically, it is characterized by cerebellar vermian hypoplasia/aplasia, thickened and reoriented superior cerebellar peduncles, and an abnormally large interpeduncular fossa, giving the appearance of a molar tooth on transaxial slices (molar tooth sign). Additional variable features include retinal dystrophy and renal disease.

Hydrolethalus syndrome 1 (HLS1): A lethal syndrome characterized by polydactyly, central nervous system malformation, and hydrocephalus. The polydactyly is postaxial in the hands and preaxial in the feet. A highly characteristic hallux duplex is seen in almost no other situation. In half of the cases, a large atrioventricular communis defect of the heart is found. The pregnancy is characterized by hydramnios, which is often massive, and by preterm delivery. [MIM:236680]
