This classification grouped primary hyperlipidaemias into types I-V based on the pattern of abnormal lipid levels due to disturbances in underlying lipoprotein metabolism. (pulsenotes.com)
The condition described in the North American literature as primary progressive aphasia and that described in the European literature as frontal dementia have been combined under the term frontotemporal lobe dementia (FTD) or frontotemporal lobar degeneration (FTLD). (medscape.com)

Becker muscular dystrophy (BMD) is characterized by later-onset skeletal muscle weakness. (beds.ac.uk)
The onset of weakness ranges from before birth to adulthood. (beds.ac.uk)
Muscular dystrophy refers to a group of more than 30 inherited (genetic) conditions that cause muscle weakness. (clevelandclinic.org)

Inheriting two copies of the risk variant may make the risk higher or the condition more severe. (wisdompanel.com)

Duchenne, a French physician, initially described a condition of progressive lethal wasting of degenerative skeletal muscle, which was later referred to as Duchenne muscular dystrophy. (medscape.com)

Serum creatine kinase level is complementary, and may be significantly elevated in some forms of LGMD, especially the autosomal recessive LGMDs. (medscape.com)

Most forms of CMD are inherited as autosomal recessive traits. (rarediseases.org)
Highly penetrant mutations, such as those in the BRCA1 or MSH2 gene, are the most prominent examples of genetic traits causing a cancer predisposition. (cdc.gov)

Lens opacities have a later, more juvenile onset and the lens opacities are located in a lamellar distribution in superficial cortical layers. (arizona.edu)
Juvenile onset (before age 20 years). (beds.ac.uk)

Although preconception reproductive genetic carrier screening (RGCS) is preferred to screening during pregnancy, population-wide preconception screening is not routinely performed in the U.S. We explored the multilevel barriers to the widespread adoption of preconception RGCS in the U.S. via key informant interviews. (cdc.gov)
The gonadotropins, luteinizing hormone (LH) and follicle-stimulating hormone in turn act on peripheral reproductive organs to regulate the onset of puberty, gametogenesis and estrous cycling [ 13 ]. (karger.com)
Telemedicine is a particularly good fit for reproductive and prenatal genetic counseling services for two main reasons. (genomemedical.com)

Onset is typically in young adulthood and may become less common after 50 years old. (wikipedia.org)
Onset for HbH ranges from first years of life to adulthood. (preventiongenetics.com)

MD shows a genetic predisposition and a family history is found in 10% cases, with an autosomal dominant inheritance pattern. (medscape.com)

NF1 and NF2 are known as "autosomal dominant," which means that they arise from an abnormal gene inherited from a parent, even though the matching gene from the other parent is normal. (genomemedical.com)

The progressive neurological deficits result in death from debilitation within 10 to 30 years of onset. (nih.gov)

Neurofibromatosis type 1 is a very common genetic condition. (vic.gov.au)
In the latter forms, there may also be a histopathologic continuum with CCD due to dominant RYR1 mutations, reflecting the common genetic background. (biomedcentral.com)
Infertility is a complex yet common medical condition. (genomemedical.com)

Anticipation tends to be more prominent when the ATXN2 gene is inherited from a person's father (paternal inheritance) than when it is inherited from a person's mother (maternal inheritance). (nih.gov)

A life threatening condition due to inadequate concentration of glucocorticoids characterized by loss of vascular tone leading to hypotension, tachycardia, and eventual cardiovascular collapse. (nih.gov)
