What's the cause of cat called syndrome
The cytogenetic characteristic is the partial loss of the long end of the chromosomal chromosomal no. 5 (5p-). The causes of chromosome aberration are:
1 physical factors: x-ray, ionizing radiation, etc。
2 chemical factors: chemical substances such as metabolism, epilepsy, pesticides, toxins such as benzene, benzo, arsenic, etc。
3. Biological factors: infections of micro-organisms such as bow worms, rubella virus, megacell virus, measles virus, mumps virus, etc。
4. Older pregnant women。
Cat called syndrome
Cats call syndrome clinical symptoms:
Cats cry out loud: the character of infant and early childhood。
2. Special faces: small heads, asymmetrical round moon faces, in a state of shock; wideness of eye range, corrosive skin, oscillation under eye angles, oscillation, cataracts, optic atrophy; the nose is wide, the jaws are small, the lips are laced, the ears are low, the growth is stunted and the neck is short。
3. The nervous system: low muscles during the neonatal period, apparent mental retardation, mental retardation, if only after two years of age, independent walking after four years of age, excess movement and destructive behaviour after adulthood。
4 other: stunting, congenital heart disease (50%); the palm is short, with a finger, a straight line, a dislocated hip, a half-vertebrae, a periverte; kidney spleen is missing, such as a urethral fracture, a hidden testicle, groin, etc。
Other common symptoms include low muscle tension, small brain disorders, stunting, round face, swelling cheeks, small chins, excessive separation of eyes, internal skin, upper and lower eyelids, tilt, flat nose, lower mouth, low ears, short fingers, broken palms, congenital heart disease. For example, heart spacing is impaired, heart spacing is impaired, artery catheters are not closed, and the fertility of people with cat crying is not affected. Less common symptoms include hare lips, jaw fractures, fistulas on the side of the ear, poor development of the chest, incomplete intestinal retours, giant colones, groin giraffes, disassembly hips, invisibility of the testes, urethra fractures, and rare kidney malformations. For example, horseshoe kidneys, kidney heterogenesis, stunted kidneys, adhesive fluids, end-finger bends, foot-touching, flat feet, second and third fingers and toes, joints that can be stretched too far。
Cats call syndrome
Cats call syndrome, the main hazards are:
1. Feeding problems due to difficulty of swallowing and sucking。
Low birth weight and slow growth。
3. Severe cognitive, linguistic and sports delays。
4. Behavioural problems include hyperactivity disorder, aggression, anger, repeated actions。
5. Specific facial features over time。
6. Severe saliva。
Cats are called syndrome therapy
There is no special treatment。
Cats are called syndrome prognosis
Mortality rates are low, and many patients survive to adulthood, but they are underweight and tall。
Cats are called syndrome prevention
High-risk pregnant women can be diagnosed with ante-natal chromosomal examination of a sheep water cell or a velvet membrane cell。
