Spinal muscular atrophy
Bohatá, Jana ; Šolc, Roman (advisor) ; Brynychová, Iva (referee)
Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder which affects α-motor neurons in anterior horns of spinal cord resulting in progressive muscle weakness. The estimated incidence is 1:10 000 and carrier frequency 1:40-1:60. SMA is classified into four grades depending on the age of onset and its severity. Life expectancy differs according to grade of SMA, patients suffering from the most serious grades live about two years, milder could live to adulthood. This disorder is caused by mutation of the SMN1 gene which is located on the fifth chromosome. In the majority of cases the type of mutation is homozygous deletion in SMN1 gene. Keywords: Spinal muscular atrophy; neuromuscular disorder; alpha motor neurons; autosomal recessive disorder; SMN1; SMN2

Anomálie oka kolií (CEA) a progresivní retinální atrofie (PRA) u australského ovčáka
VAŇKOVÁ, Adéla
This bachelor thesis summarizes the knowledge about two important hereditary eye diseases of Australian Shepherd. The thesis reviews the genetic basis of the diseases, symptoms and possible prophylaxis of the Collie eye anomaly and progressive retinal atrophy. Collie eye anomaly affects the sclera, choroid, retina including blood vessel and eye nerve discus. Progressive retinal atrophy affects the retina, either whole or its central part. These diseases, often connected with an autosomal recessive hereditary pattern, are harmful to affected individuals, as it ends up with blindness.
