Silver-Russell syndrome (SRS) is a rare genetic disorder characterized by slow growth before and after birth, distinctive facial features, and other physical problems. It is caused by a genetic abnormality known as maternal uniparental disomy of chromosome 7 (UPD7). UPD7 occurs when a person has two copies of chromosome 7 from the same parent, instead of one copy from each parent. This abnormality can lead to a variety of physical and developmental problems, including those seen in SRS.

The symptoms of Silver-Russell syndrome due to maternal uniparental disomy of chromosome 7 can vary from person to person, but may include:

- Low birth weight and slow growth
- Small head size (microcephaly)
- Delayed development
- Abnormal facial features, such as a triangular-shaped face, a small lower jaw, and a prominent forehead
- Intellectual disability
- Behavioral problems
- Poor feeding
- Constipation
- Hypoglycemia
- Hypothyroidism
- Heart defects
- Kidney abnormalities
- Skeletal abnormalities, such as Scoliosis and curved pinky fingers

Silver-Russell syndrome (SRS) due to maternal uniparental disomy of chromosome 7 (mUPD7) is caused by a genetic abnormality in which both copies of chromosome 7 are inherited from the mother. This abnormality is thought to be caused by a process called meiotic non-disjunction, in which the chromosomes fail to separate properly during the formation of egg or sperm cells. This results in an embryo with two copies of chromosome 7 from the mother, instead of one from each parent. The exact cause of this meiotic non-disjunction is unknown, but it is thought to be due to a combination of genetic and environmental factors.

1. Growth hormone therapy: Growth hormone therapy is the most common treatment for Silver-Russell syndrome due to maternal uniparental disomy of chromosome 7. Growth hormone therapy helps to stimulate growth and can help to improve the physical features associated with Silver-Russell syndrome.

2. Nutritional therapy: Nutritional therapy is important for children with Silver-Russell syndrome due to maternal uniparental disomy of chromosome 7. This includes providing a balanced diet with adequate calories and nutrients to support growth and development.

3. Physical therapy: Physical therapy can help to improve muscle strength and coordination, as well as posture and balance.

4. Speech therapy: Speech therapy can help to improve communication skills and language development.

5. Occupational therapy: Occupational therapy can help to improve fine motor skills and daily living activities.

At this time, there is no cure for Silver-Russell syndrome due to maternal uniparental disomy of chromosome 7. However, there are medications and treatments available to help manage the symptoms of the condition. These include growth hormone therapy, nutritional supplements, and medications to help with sleep, behavior, and appetite. Additionally, physical and occupational therapy can help with motor skills and development.
