چکیده
Objective: HYBID (Hyaluronan Binding Protein Involved in HA Depolymerization, KIAA1199) is a hyaluronan (HA) binding protein, which involves in depolymerization of HA. It is reported that HYBID mRNA is expressed in the lung, heart, skin and brain in murine and human. However, the role of HYBID in the brain remains unclear. In this study, we have made HYBID KO mice and evaluated its function in the central nervous system. Methods: To investigate the role of HYBID in brain, behavioral tests were performed by using HYBID KO mice. In situ hybridization was performed to investigate the localization of HYBID mRNA in mouse brain. Results: HYBID mRNA was expressed in the brain, especially hippocampus and cerebellum in wild-type mice, but not KO. HYBID KO mice showed decreased memory ability in a novel object recognition test. The expression of Hyal1 and Hyal2 mRNAs was not changed in the HYBID KO mouse brain. These results suggest that HYBID plays a key role in memory function in the brain. Conclusion: HYBID may be involved in brain function, such as memory and learning. Policy of Full Disclosure: None.

Association of mtDNA mutation with Autism in Iranian patients
The autism spectrum disorders (ASD) are amongst the most heritable complex disorders. Although there have been many efforts to locate the genes associated with ASD risk, many has been remained to be disclosed about the genetics of ASD. Scrutiny's have only disclosed a small number of de novo and inherited variants significantly associated with susceptibility to ASD. These only comprise a small ...

A Novel Nonsense mutation in PANK2 Gene in Two Patients with Pantothenate Kinase-Associated Neurodegeneration
Pantothenate kinase- associated neurodegeneration (PKAN) syndrome is a rare autosomal recessive disorder characterized by progressive extrapyramidal dysfunction and iron accumulation in the brain and axonal spheroids in the central nervous system. It has been shown that the disorder is caused by mutations in PANK2 gene which codes for a mitochondrial enzyme participating in coenzyme A biosynthe...

Backgrounds: Hypohidrotic ectodermal dysplasia (HED) is a rare genetic disorder, distinguished by hypotrichosis, hypohidrosis, and hypodontia. HDE can be inherited in X-linked recessive manner as a result of mutations in the ectodysplasin A (EDA) gene as well as autosomal dominant and autosomal recessive manners both of them caused by mutations in EDA receptor (EDAR) and EDAR-associated death d...
