Her thyroid function is well controlled with a 5-mg dose of methimazole 3 times daily. She was initially treated with propylthiouracil but was switched to methimazole owing to urticaria. I have heard about birth defects in infants whose mothers used methimazole during pregnancy. How safe is it? Methimazole is widely used in Europe, South America, and Asia, and is an alternative for patients who cannot tolerate propylthiouracil. Some case reports raised concern about fetal toxicity from methimazole, which is reportedly characterized by aplasia cutis, esophageal atresia, choanal atresia, facial abnormalities, and mental retardation. However, causality is unclear and the overall risk of congenital abnormalities in infants exposed to methimazole in utero was not higher than in those exposed to nonteratogenic drugs in cohort studies. It is important for a pregnant woman to continue methimazole, if necessary, because uncontrolled hyperthyroidism increases the risk of complications such as preterm labour and low birth weight. Hyperthyroidism occurs in 1 to 2 of every pregnant women. Other causes include functioning adenoma, thyroiditis, and excessive thyroid hormone intake. Clinical practice guidelines for the management of hyperthyroidism during pregnancy have been developed by academic societies, including the Endocrine Society, American Association of Clinical Endocrinologists, and American College of Obstetricians and Gynecologists. Placental human chorionic gonadotropin is structurally similar to thyroid-stimulating hormone TSH , and the increase in human chorionic gonadotropin in the first trimester has been suggested to be the cause of thyroid stimulation.

Genetic studies have suggested the involvement of contactins 4, 5 and 6 in the ASDs, but no functional study has confirmed this hypothesis. The present work combines a genetic analysis, a functional analysis on cultured primary rat cortical neurons and a structural analysis by molecular modelling.

Private variants present only in one individual or one family are enriched in patients compared to controls. CNVs and SNVs are inherited, mainly from unaffected parents, which suggests that impairments in contactins represent susceptibility factors for ASDs, rather than causal factors.

We therefore analysed, on several hundreds of neurons per condition, the length and branching of neurites in a co-culture system with HEK cells overexpressing a CNTN protein. The last aim of the present study consisted in evaluating the influence of some of these variants on the interaction of CNTNs, via their immunoglobulin Ig domains 2 and 3, with one of their ligands, the protein tyrosine phosphatase receptor PTPRG. We have thus been able to predict that some variants were likely to alter ionic bonds or steric constraints in this interaction module.

Taken as a whole, our results demonstrate that several rare CNTN variants found in patients with ASD have deleterious functional effects.

Limb anomalies in the CHARGE association.

The presence of these rare variants in unaffected relatives indicates that CNTN impairments fit into a "multiple hit" model, according to which autism may result from the combination of several genetic defects, each being a risk factor with moderate effect but not triggering, in itself, the development of the disorder.

Dieses Krankheitsbild ist durch progeroiden Aspekt, Cutis laxa, intrauterinen Minderwuchs und psychomotorische Retardierung charakterisiert. In der genetischen Untersuchung stellten sich ein normaler Karyotyp und kein Hinweis auf eine chromosomale Aberration dar. Die Genese des LMS ist bisher noch unklar.
