LZTFL1
Developmental stage
Expressed in brain, lung, liver, and kidney.
Function
Regulates ciliary localization of the BBSome complex. Together with the BBSome complex, controls SMO ciliary trafficking and contributes to the sonic hedgehog (SHH) pathway regulation. May play a role in neurite outgrowth. May have tumor suppressor function.
Involvement in disease
Bardet-Biedl syndrome 17
BBS17
A syndrome characterized by usually severe pigmentary retinopathy, early-onset obesity, polydactyly, hypogenitalism, renal malformation and intellectual disability. Secondary features include diabetes mellitus, hypertension and congenital heart disease. Bardet-Biedl syndrome inheritance is autosomal recessive, but three mutated alleles (two at one locus, and a third at a second locus) may be required for clinical manifestation of some forms of the disease.
None
The disease is caused by variants affecting the gene represented in this entry. Patients carrying LZTFL1 mutations manifest mesoaxial polydactyly, a clinical feature very uncommon for Bardet-Biedl syndrome (PubMed:22510444, PubMed:23692385). Some patients manifest situs inversus (PubMed:22510444).
Sequence Similarities
Belongs to the LZTFL1 family.
Tissue Specificity
Expressed in prostate, ovary, stomach, pancreas, esophagus, breast, liver, bladder, kidney, thyroid, colon and lung (at protein level). Down-regulated in multiple primary tumors (at protein level). Detected in testis, heart, skeletal muscle, thymus, spleen, small intestine, and peripheral blood leukocytes.
