Summary
Autopsies of two Myhre syndrome patients revealed widespread organ fibrosis and previously undocumented neuropathologic findings. Postmortem examinations are crucial for understanding this rare multisystem disorder and guiding patient care.
Area of Science:
- Pathology
- Genetics
- Rare Diseases
Background:
- Myhre syndrome (OMIM 139201) is an ultra-rare multisystem disorder with limited pathological data due to scarce postmortem examinations.
- Morbidity is associated with severe congenital heart defects, aortic hypoplasia, airway stenosis, constrictive pericarditis, and restrictive cardiomyopathy.

Cardiomyopathy III: Hypertrophic Cardiomyopathy
374
Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...

The Ratio of X Chromosome to Autosomes
9.4K
In most organisms, sex is determined by the ratio of X and Y chromosomes. However, in some organisms, such as Drosophila and C.elegans, sex is determined by the ratio of the number of X chromosomes to the number of sets of autosomes. The Y chromosome in Drosophila is active but does not determine sex. It contains genes responsible for the production of sperms in adult flies.
Normal male Drosophila has a ratio of one X chromosome to two sets of autosomes. In contrast, normal female...
