What are the signs and symptoms of Hydrops, Ectopic calcification, Moth-eaten skeletal dysplasia? The diagnostic findings of HEM (hydrops fetalis, severe micromelia, and ectopic calcification) have been present in all cases reported in the medical literature thus far. The following are several of the other signs and symptoms that have been reported in some patients with HEM : Polydactyly (presence of more than 5 fingers on the hands or 5 toes on the feet) Reduced number of ribs Omphalocele Intestinal malformation Abnormal fingernails Less than normal number of lobes in the lung (hypolobated lungs) Cystic hygroma The Human Phenotype Ontology provides the following list of signs and symptoms for Hydrops, Ectopic calcification, Moth-eaten skeletal dysplasia. 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.

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.
