answer:What are the signs and symptoms of Spastic paraplegia 16? The Human Phenotype Ontology provides the following list of signs and symptoms for Spastic paraplegia 16. If the information is available, the table below includes how often the symptom is seen in people with this condition. You can use the MedlinePlus Medical Dictionary to look up the definitions for these medical terms. Signs and Symptoms Approximate number of patients (when available) Babinski sign - Facial hypotonia - Hyperreflexia - Hypoplasia of the maxilla - Intellectual disability - Juvenile onset - Low frustration tolerance - Lower limb amyotrophy - Lower limb muscle weakness - Mood swings - Motor aphasia - Restlessness - Short distal phalanx of finger - Shuffling gait - Spastic paraplegia - Strabismus - Urinary bladder sphincter dysfunction - Urinary incontinence - Urinary urgency - Visual impairment - X-linked recessive inheritance - The Human Phenotype Ontology (HPO) has collected information on how often a sign or symptom occurs in a condition. Much of this information comes from Orphanet, a European rare disease database. The frequency of a sign or symptom is usually listed as a rough estimate of the percentage of patients who have that feature. The frequency may also be listed as a fraction. The first number of the fraction is how many people had the symptom, and the second number is the total number of people who were examined in one study. For example, a frequency of 25/25 means that in a study of 25 people all patients were found to have that symptom. Because these frequencies are based on a specific study, the fractions may be different if another group of patients are examined. Sometimes, no information on frequency is available. In these cases, the sign or symptom may be rare or common.

answer:Pyruvate carboxylase deficiency is an inherited disorder that causes lactic acid and other potentially toxic compounds to accumulate in the blood. High levels of these substances can damage the body's organs and tissues, particularly in the nervous system. Researchers have identified at least three types of pyruvate carboxylase deficiency, types A, B, and C, which are distinguished by the severity of their signs and symptoms. This condition is caused by mutations in the PC gene and inherited in an autosomal recessive pattern.

answer:How is pyruvate carboxylase deficiency inherited? Pyruvate carboxylase deficiency is inherited in an autosomal recessive manner. This means that both copies of the disease-causing gene in each cell (usually one inherited from each parent) must have a mutation for an individual to be affected. Individuals who carry one mutated copy of the gene are referred to as carriers. Carriers typically do not have any signs or symptoms of the condition. When two carriers for an autosomal recessive condition have children, each child has a 25% (1 in 4) risk to have the condition, a 50% (1 in 2) risk to be an unaffected carrier like each of the parents, and a 25% risk to not have the condition and not be a carrier (i.e. to inherit both normal genes). In other words, each child born to two carriers has a 75% (3 in 4) chance to be unaffected. De novo mutations (new mutations that occur for the first time in an individual and are not inherited from a parent) have been reported for this condition. This means that in some cases, an affected individual may have only one parent who is a carrier for the condition. Carrier testing for at-risk relatives and prenatal testing for pregnancies at increased risk may be possible through laboratories offering custom mutation analysis if the disease-causing mutations in a family are known. Individuals interested in learning more about genetic risks to themselves or family members, or about genetic testing for this condition, should speak with a genetics professional.
