1. What is it?

It refers to diseases that form during fetal development and can be caused by genetic mutations, chromosomal abnormalities, environmental factors, etc. These disorders are usually detected at birth or in infancy, although some develop gradually as they grow. According to the Hong Kong Health Bureau, about 3-5% of newborns suffer from varying degrees, and common types include:

• Congenital heart disease: All occupy one of the most common types about 1%
• Down’s syndrome: About 40 to 50 cases are confirmed in Hong Kong every year
• Spina bifida: The incidence rate is about 3 to 4 per 10,000 births
• Congenital metabolic disorders: Phenylketonuria (PKU), etc.

The causes of congenital diseases are complex and mainly include:海外睇醫生

• Hereditary factors: Chromosomal abnormalities, monogenic genetic diseases, etc., account for about 40-60%
• Environmental factors: Pregnancy infections (rubella, cytomegalovirus), drug exposure, radiation, etc.
• Multi-factor interaction: Genes and environment affect together

When choosing the right insurance plan, pay special attention to the coverage associated with congenital diseases, as it can affect your future child's medical coverage.

2. Should babies be screened for congenital diseases?

Screening for congenital diseases is an important part of modern neonatal care. The Hong Kong Health Bureau has been implementing a newborn screening program since the 1980s and currently covers about 30 congenital diseases. The benefits of early screening are significant.

Babies with the following symptoms require special attention to screening:

• Family history of congenital diseases
• Mothers over 35 years old (elderly mothers)
• History of infection or exposure to teratogenic factors during pregnancy
• Ultrasound revealed abnormalities

For plansSee a doctor abroadScreening items and standards may vary depending on the country, so it is recommended to research the newborn screening policy of the destination country in advance. Some countries may offer more comprehensive screening programs, but additional costs are also considered.

3. Common diagnostic methods for congenital diseases

1. Prenatal diagnosis

With the rapid development of prenatal diagnostic technology in recent years, public hospitals in Hong Kong provide the following major tests:

• Non-invasive prenatal testing (NIPT): 99% accuracy in fetal DNA analysis with maternal blood, suitable for screening for chromosomal abnormalities such as Down syndrome
• Amniotic fluid puncture: It is carried out at 16-20 weeks, the diagnosis is the most accurate, but there is a risk of miscarriage of about 0.5%
• Village Sampling: It can be performed in 10-13 weeks and gives results faster than amniocentesis

2. Newborn screening

All newborns in Hong Kong should undergo the following basic screening tests:

• Heel blood screening: Detection of 6 metabolic diseases collected at 48 hours after birth
• Hearing Screening: Use otoacoustic radiation or automated auditory brainstem response test
• Echocardiography: Screening for severe congenital heart disease

3. Genetic testing

If a specific genetic disorder is suspected, genetic testing is the basis for confirmation. Hong Kong's hospitals and private sector offer:

• Whole exome sequencing (WES)
• Chromosomal microarray analysis (CMA)
• Specific gene panel assays

2. Join patient groups and support each other

There are several congenital disease support organisations in Hong Kong, including:

• Hong Kong Down Syndrome Association
• Hong Kong Mucopolysaccharidosis and Rare Genetic Diseases Mutual Aid Group
• Hong Kong Tuberous Sclerosis Society
