In context of Amniocentesis,which of the following statement is incorrect ?a)It can be used for detection of Cleft palate.b)It is usually done when a woman is between 14 -16 weeks pregnant.c)It is used for prenatal sex determination.d)It can be used for detection of Down syndrome.Correct answer is option 'A'. Can you explain this answer?

Question

Answer

Amino centesis is a medical procedure used in parental diagnosis of chromosomal and genetic abnormalities such as down's syndrome.
turner's syndrome, etc. it also helps in parental sex determination,hence there is a statutory ban on it to female faeticide. it is done when women is 14-16 months pregnant. it does not help in detection of cleft palate.
cleft palate can be detected only by parental ultrasound as early as 16 weeks into a pregnancy. the diagnosis is then confirmed at birth with a detailed visual assessment and physical examination.

Answer

Only genetical deformatis can be guesssed by amminocentosis not congenital although genetical disorder are congenital but cleft palate are not genetical disorder.

Answer

Incorrect statement: It can be used for detection of Cleft palate.

Explanation:
Amniocentesis is a prenatal diagnostic procedure that involves the collection of a small amount of amniotic fluid from the amniotic sac surrounding the fetus. This fluid contains fetal cells and various substances that can provide valuable information about the health and development of the baby.

1. Purpose and Timing of Amniocentesis:
Amniocentesis is typically performed between 14 and 16 weeks of pregnancy. It is a diagnostic test used to detect certain genetic and chromosomal abnormalities in the fetus. The procedure is usually recommended for women who have an increased risk of having a baby with a genetic disorder, such as advanced maternal age (35 years or older), a previous child with a genetic abnormality, or a family history of certain genetic conditions.

2. Conditions Detected by Amniocentesis:
Amniocentesis can detect various genetic and chromosomal abnormalities, including:

- Down syndrome (trisomy 21): This is one of the most common chromosomal abnormalities. It is caused by the presence of an extra copy of chromosome 21.
- Genetic disorders: Amniocentesis can detect certain genetic disorders caused by mutations in specific genes.
- Neural tube defects: Although not always definitive, amniocentesis can sometimes detect neural tube defects such as spina bifida or anencephaly.
- Chromosomal abnormalities: In addition to Down syndrome, amniocentesis can identify other chromosomal abnormalities, such as trisomy 18 (Edwards syndrome) and trisomy 13 (Patau syndrome).

3. Cleft Palate:
Cleft palate is a congenital condition characterized by a gap or split in the roof of the mouth. While amniocentesis can provide valuable information about the genetic health of the fetus, it is not specifically designed to detect cleft palate. The diagnosis of cleft palate is typically made through a combination of prenatal ultrasound, physical examination after birth, and sometimes genetic testing.

In conclusion, the incorrect statement is that amniocentesis can be used for the detection of cleft palate. Amniocentesis is primarily used for the detection of genetic and chromosomal abnormalities, such as Down syndrome, and is not specifically designed for the diagnosis of cleft palate.

Answer

Amniocentesis involves analysing foetal chromosomes to determine any genetic disorder in foetus. Cleft palate is a congenital or birth defect, it can be diagnosed by prenatal ultrasound.
