Background3MC1 syndrome is a rare autosomal recessive disorder characterized by intellectual disability, short stature and distinct craniofacial, umbilical, and sacral anomalies. Five mutations in MASP1, encoding lectin complement pathway enzymes MASP-1 and MASP-3, have thus far been reported to cause 3MC1 syndrome. Only one previously reported mutation affects both MASP-1 and MASP-3, while the other mutations affect only MASP-3.MethodsWe evaluated six unrelated individuals with 3MC1 syndrome and performed Sanger sequencing for all coding exons of MASP1. We also measured complement lectin and alternative pathway activities in an affected individual’s serum.ResultsWe found two novel splice site mutations, c.1012-2A > G in one and c.891 + 1G > T in two probands, and three novel missense mutations, c.1451G > A (p.G484E), c.1657G > A (p.D553N), and c.1987G > T (p.D663Y). Missense mutations affect only MASP-3, while splice site mutations affect both MASP-1 and MASP-3. In a proband who is homozygous for c.891 + 1G > T, we detected a total lack of lectin complement pathway activity and a 2.5-fold lower alternative pathway activity. The phenotype observed in patients whose both MASP-1 and MASP-3 are affected and in those whose only MASP-3 is affected does not appear to be different. We observed structural brain abnormalities, neonatal tooth, a vascular anomaly and a solid lesion in liver as novel phenotypic features of 3MC1 syndrome.ConclusionNovel mutations and additional phenotypic features expand the genotypic and phenotypic spectrum of 3MC1 syndrome. Although patients with MASP-1 dysfunction in addition to disrupted MASP-3 have an altered complement system, their disease phenotype is not different from those having only MASP-3 dysfunction.Electronic supplementary materialThe online version of this article (doi:10.1186/s13023-015-0345-3) contains supplementary material, which is available to authorized users.
Objective: Both asthma and vitamin D deficiency are common among children. The results from studies examining the relationship between them are contradictory. The aim of this study is to determine the relationship between the clinical parameters of asthma and vitamin D status in children. Methods: One hundred and twenty children diagnosed with asthma and followed-up in our hospital were included in the study. The control group included 74 children with no evidence of allergic disease. The eosinophil counts, IgE levels and serum 25 OH cholecalciferol [25(OH)D] levels were measured. Results: The patient group consisted of 73 (60.8%) males and 47 (39.2%) females with a mean age of 4.4 ± 1.2 years. There was no significant difference between the patient and control groups with respect to gender and age. The mean 25(OH)D level was 21.49 ± 7.74 ng/ml in the study group and 23.94 ± 8.97 ng/ml in the control group, and this difference was not significant (p = 0.094). The patients with asthma were grouped according to their vitamin D status as ‘deficient' (group 1), ‘insufficient' (group 2) and ‘normal' (group 3). The sociodemographic features, duration of illness, number of hospitalizations, number of sensitivities to allergens, eosinophil count and serum IgE levels were not found to be different between the groups. However, the total number of exacerbations, asthma severity and systemic glucocorticoid need in the previous year were significantly higher in the deficiency group (p < 0.05). Conclusion: Vitamin D levels were not significantly different in patients with asthma. Vitamin D deficiency was common in the study group as well as in the control group. The clinical severity of disease, the number of exacerbations and the systemic glucocorticoid need were related to vitamin D level. © 2014 S. Karger AG, Basel
In addition to diastolic dysfunction, LV longitudinal and radial function was found to be impaired in asymptomatic children and adolescents with type 1 DM who have normal LV ejection fraction by 2DSTE. Glycemic control may be the main risk factor for alteration of myocardial function.
Mean NLR is higher in asthmatic children compared to control group. We think that NLR could be used for the evaluation of systemic inflammation in asthmatic patients. However, further studies are needed to assess airway and systemic inflammation as well as NLR in patients with asthma.
46,XY complete gonadal dysgenesis (Swyer syndrome) is a rare cause of disorder of sexual development. This syndrome is caused by a defect in the determination of sex during embryogenesis and is characterised with female external genitalia, normal or rudimentary uterus, and streak gonads, despite the presence of the 46,XY karyotype. Most of the studied cases presented with leak of secondary sex characteristics and primary amenorrhea during adolescence. Laboratory findings reveal hypergonadotropic hypogonadism. Herein we present the case of a female with a 46,XY karyotype who was admitted with delayed puberty and detected to have a microdeletion in the SRY gene and diagnosed to have Swyer syndrome. We highlight the importance of karyotype analysis in patients with delayed puberty and primary amenorrhea. Once the diagnosis of 46,XY complete gonadal dysgenesis is established, early laparoscopic removal of the dysgenetic gonads is crucial to prevent the development of gonadal malignancy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
