X-linked Alport syndrome
X-linked Alport syndrome (AS) is a heritable disorder which is associated with mutations in the type IV collagen oc5(IV) chain gene (COL4A5) located on chromosome X. Following renal transplantation, an average of 6% of male AS patients develop anti-GBM nephritis. We studied the specificity of the antibodies against type IV collagen in the serum of a patient with COL4A5 partial deletion. The spe...
متن کاملX-linked scapuloperoneal syndrome.
Observations are presented on a family with muscular weakness and wasting with an onset in childhood, predominantly affecting the proximal muscles in the upper limbs and the distal muscles in the lower. This was accompanied by contractures of the elbows and by pes cavus. Pseudohypertrophy was absent. Progression was slow, but an associated cardiomyopathy developed in adult life. Investigations ...
متن کاملKallmann syndrome: MR findings.
PURPOSE To evaluate patients with known hypogonadotropic hypogonadism, some with known anosmia, for defective rhinocephalon development that resulted in olfactory tract abnormalities, an affliction known as Kallmann syndrome. METHODS Six patients who clinically had hypogonadotropic hypogonadism were examined by MR. Thin coronal images of the interior frontal region were used to determine pres...
متن کاملMRI findings in Kallmann syndrome.
Kallmann syndrome (KS) is a neuronal migration disorder characterised by hypogonadotrophic hypogonadism and anosmia or hyposmia. Five patients with clinical findings suggestive of KS were evaluated with MRI. All patients had abnormalities of olfactory system. Olfactory bulbs were absent in all patients. Olfactory sulci were absent in 3 patients and hypoplastic in 2 patients. Anterior pituitary ...
متن کاملAnosmin-1, Defective in the X-Linked Form of Kallmann Syndrome, Promotes Axonal Branch Formation from Olfactory Bulb Output Neurons
The physiological role of anosmin-1, defective in the X chromosome-linked form of Kallmann syndrome, is not yet known. Here, we show that anti-anosmin-1 antibodies block the formation of the collateral branches of rat olfactory bulb output neurons (mitral and tufted cells) in organotypic cultures. Moreover, anosmin-1 greatly enhances axonal branching of these dissociated neurons in culture. In ...
