Bardet-Biedl syndrome 22

A form of Bardet-Biedl syndrome, a syndrome characterized by usually severe pigmentary retinopathy, early-onset obesity, polydactyly, hypogenitalism, renal malformation and intellectual disability. Secondary features include diabetes mellitus, hypertension and congenital heart disease. Bardet-Biedl syndrome inheritance is autosomal recessive, but three mutated alleles (two at one locus, and a third at a second locus) may be required for clinical manifestation of some forms of the disease.

Spermatogenic failure 84

An autosomal recessive male infertility disorder characterized by multiple morphologic abnormalities of the sperm flagella, resulting in severely reduced motility. Some patients also have a reduced sperm count.

Spermatogenic failure, X-linked, 3

An infertility disorder characterized by asthenoteratozoospermia. Spermatozoa exhibit multiple morphologic abnormalities, including absent, short, coiled, and irregular-caliber flagella.

Spermatogenic failure 65

An autosomal recessive male infertility disorder characterized by asthenoteratozoospermia. Progressive sperm motility is severely reduced or absent due to multiple morphologic abnormalities of the flagella.

Spermatogenic failure 90

An autosomal recessive male infertility disorder due to severely reduced progressive motility of sperm.

Spermatogenic failure 82

An autosomal recessive male infertility disorder characterized by asthenoteratozoospermia and multiple morphologic abnormalities of the sperm flagella.

Spermatogenic failure 56

An autosomal recessive male infertility disorder characterized by severely reduced sperm motility, due to multiple morphologic abnormalities of the flagella.

Spermatogenic failure 5

An infertility disorder caused by spermatogenesis defects. Semen from affected men show close to 100% morphologically abnormal multiflagellar spermatozoa with low motility, oversized irregular heads, and abnormal midpiece and acrosome.
