Is clinodactyly dominant?
Diagnosis and Pathology Clinodactyly presents most commonly as an isolated radial inclination of the small finger, because of the middle phalanx adopting a triangular18 or trapezoidal shape. This form of clinodactyly is inherited as an autosomal dominant trait and is often bilateral.
Are bent pinkies dominant or recessive?
Bent Little Finger (L): A dominant allele results in the end joint of the little finger of each hand bending inward. Straight little fingers are a result of the recessive genotype.
What does clinodactyly mean?
Clinodactyly means that your child has an abnormally bent or curved finger. It is typically caused by abnormal growth and development of the small bones of the finger.
What is clinodactyly associated with?
Clinodactyly is caused by a developmental defect in the bones of the finger. This defect causes the bone to make a wedge shape instead of a normal rectangle. Clinodactyly can be associated with many syndromes including Down syndrome, Klinefelter syndrome, Turner syndrome, Fanconi anemia and others.
Is clinodactyly a birth defect?
Causes. Clinodactyly is a congenital condition, meaning it is present at birth even if it is not discovered until later. Clinodactyly can be inherited, or your child may be the first person in your family to have the condition.
Is clinodactyly a disability?
Clinodactyly itself is benign, but it is frequently associated with learning disabilities and behavioral disorders. It is considered a soft sign in the diagnosis of these conditions. Indeed, all developmental/behavioral pediatricians look for clinodactyly during their initial evaluation.
Does clinodactyly mean Down syndrome?
Clinodactyly is the medical term for an abnormally bent or curved finger. The affected finger abnormally curves to the side and may overlap other fingers. While the condition is relatively rare among the general population (3 percent), it affects one in four children born with Down syndrome (trisomy 21).
Can clinodactyly be corrected?
What are the treatment options? Because clinodactyly usually causes no symptoms and doesn’t severely restrict the use of the affected finger, your child’s doctor may not recommend any treatment. Splinting the finger with a neighboring finger to help straighten it isn’t recommended.
Can you fix clinodactyly without surgery?
TREATMENT. Most cases of clinodactyly do not require surgical intervention. Observation of the deformity is indicated when there are no functional limitations. Up to 10 degrees of deviation of the thumb and small finger is considered normal.
