1q44 microdeletion syndrome is a rare genetic disorder caused by a deletion of genetic material on the long arm of chromosome 1. It is characterized by intellectual disability, developmental delay, and a variety of physical features. Other features may include seizures, hypotonia, facial dysmorphism, and hearing loss.

The symptoms of 1q44 microdeletion syndrome vary from person to person, but may include:

-Developmental delay
-Intellectual disability
-Speech delay
-Seizures
-Growth delays
-Feeding difficulties
-Behavioral problems
-Abnormal facial features
-Hearing loss
-Heart defects
-Kidney abnormalities
-Gastrointestinal problems
-Skeletal abnormalities
-Hypotonia (low muscle tone)
-Vision problems

1q44 microdeletion syndrome is caused by a deletion of genetic material on the long arm of chromosome 1. This deletion is usually inherited from a parent, but can also occur spontaneously. The exact cause of the deletion is unknown, but it is thought to be due to a random error during the formation of reproductive cells.

1q44 microdeletion syndrome is a rare genetic disorder, and there is currently no known cure. Treatment is focused on managing the symptoms and complications associated with the disorder. This may include physical therapy, occupational therapy, speech therapy, and special education services. Other treatments may include medications to help with seizures, behavioral issues, and sleep disturbances. In some cases, surgery may be necessary to correct physical abnormalities. Genetic counseling is also recommended for families affected by 1q44 microdeletion syndrome.

1. Advanced maternal age
2. Family history of chromosomal abnormalities
3. Abnormal prenatal ultrasound
4. Abnormal maternal serum screening
5. Abnormal amniocentesis results
6. Abnormal fetal karyotype results

At this time, there is no cure for 1q44 microdeletion syndrome. However, there are medications and therapies that can help manage the symptoms associated with the condition. These include medications to help with seizures, physical and occupational therapy to help with motor skills, speech therapy to help with communication, and behavioral therapy to help with social skills.
