Objective: The study aimed to show the clinical characteristics and prognosis of the L1 syndrome in patients with L1CAM mutations in the extracellular region.
Materials And Methods: Three affected boys and their siblings and parents from a large family were included in this study. Genetic etiology was investigated by whole-exome sequencing in the index patient.
Background: Phosphatase and tensin homolog (PTEN) germline mutations are associated with cancer syndromes (PTEN hamartoma tumor syndrome; PHTS) and in pediatric patients with autism spectrum disorder (ASD) and macrocephaly. The exact prevalence of PTEN mutations in patients with ASD and macrocephaly is uncertain; with prevalence rates ranging from 1% to 17%. Most studies are retrospective and contain more adult than pediatric patients, there is a need for more prospective pediatric studies.

Although important, the molecular mechanisms controlling cardiac TLR genes expression have not been clearly addressed. This study examined the expression pattern of , , , , , , , , and in normal and disease-stressed mouse hearts.

Recessive mutations in the GNPTAB gene have been associated with MLIIIalpha/beta. We present five children aged 9-16 years from a large kindred family whose serum activities of several lysosomal enzymes were significantly elevated.

EFR3A is a critical component of a protein complex required for the synthesis of the phosphoinositide PtdIns4P, which has a variety of functions at the neural synapse. We hypothesized that deleterious mutations in EFR3A would be significantly associated with ASD.
