Enfermedad antimembrana basal glomerular en un paciente transplantado renal con enfermedad de Alport. Research output: Contribution to journal › Article. Pero el conocimiento molecular de estas enfermedades ha hecho que podamos agruparlas bajo otros epígrafes, como son: síndrome de Alport ligado al sexo.

I, classic juvenile Alport syndrome with deafness; II, X-linked juvenile Alport syndrome with deafness; III, X-linked adult Alport syndrome with deafness; IV, X-linked adult Alport syndrome without deafness or other defect, that is, purely renal disease; V, autosomal Alport syndrome with deafness and thrombocytopathia see ; and VI, autosomal recessive juvenile Alport syndrome with deafness Hereditary nephritis with nerve deafness: Hereditary familial congenital haemorrhagic nephritis: Ada Hamosh – updated: A premature stop codon in the gene encoding the alpha-5 chain of collagen type IV in canine hereditary nephritis HN.

They found a maximum lod score of 2. Hyperthyroidism was present in 1 and histologic changes of thyroiditis in a second.

The proband’s mother was known to have microhematuria. All were consistent with X-linked inheritance, which was confirmed by linkage studies. A cadaveric kidney transplantation was done 2 years later.

In 2 of them, enermedad episodes over a period of 1 to 3 years had occurred; the third brother had approximately 60 episodes over the previous 10 years. Lod scores in excess of 3. Hereditary nephropathy with hearing loss: Men were more severely affected than women. Anterior lenticonus and Alport’s syndrome.

They commented that an alternative explanation could be the involvement of other genes within the Xq region. Light microscopy and immunohistochemistry using a monoclonal antibody to COL4A5 were used to define expression of the protein in the glomerular enfermesad membrane. A bonus to all MIMmatch users is the option to sign up for updates on new gene-phenotype relationships.

Nielsen suggested that anterior lenticonus may be a specific sign of Alport syndrome, since all recently reported cases e. The proband had 2 daughters, aged 15 and 13 years.

Normal glomerular capillaries filter plasma through a basement membrane rich in the alpha-3, alpha-4, and alpha-5 chains of type IV collagen. Two types of Alport syndrome were represented by 3 kindreds: Pathology of hereditary nephritis.

The findings provided further evidence that Alport syndrome is a hereditary disorder of basement membranes. However, there was nefermedad evidence of linkage heterogeneity among these families.

Although initially reported as a dominant trait with possible partial sex-linkage, it later became apparent that this was an X-linked dominant condition Cohen et al.


Myers and Tyler found variability in the histologic findings of the ear in Alport syndrome. X-linked inheritance of Alport syndrome: X-linked Alport syndrome in females. Reexamination of segregation showed no excess of affected offspring of affected parents and no difference in penetrance in daughters of symptomatic and asymptomatic mothers.

There were striking urinary abnormalities in early childhood which progressed to renal failure in adulthood. Characterisation by immunoblotting of the glomerular basement membrane defect in hereditary nephritis.


Progression to renal failure was gradual and entermedad occurred in males by the fifth decade. Affected women had less obvious urinary findings and rarely developed uremia.

They reported that all different types of mutations were observed apport juvenile-type Alport syndrome whereas only glycine substitutions and splicing mutations were observed in adult-type Alport syndrome. Flinter and Bobrow studied 41 families and concluded that Alport syndrome may be less heterogeneous than previously thought. Genetics of classic Alport’s syndrome. The exception was a splice site mutation resulting in an mRNA alpor exon Affected males died early of uremia, while females lived to old age.
