Even when relaxed, muscles have a continuous and passive partial contraction which provides some resistance to passive stretching. Hypotonia thus manifests as diminished resistance to passive stretching. Hypotonia is not the same as muscle weakness, although the two conditions can co-exist.","HPO_Feature_URL__c":"https://hpo.jax.org/browse/term/HP:0001252","HPO_Synonym__c":"Low muscle tone; Low or weak muscle tone; Muscle hypotonia; Muscular hypotonia","HPO_Name__c":"Hypotonia","Feature_System__c":"Musculoskeletal System","HPO_Feature_Type__c":"Symptom"}},{"Provided_By__c":"ORPHA:2479","HPO_Frequency__c":"Occasional (5-29%)","Feature__r":{"HPO_Description__c":"Flatness of the supraorbital portion of the frontal bones.","HPO_Feature_URL__c":"https://hpo.jax.org/browse/term/HP:0009891","HPO_Synonym__c":"Depressed supraorbital margins; Depressed supraorbital ridge; Flat supraorbital margins; Flat supraorbital ridge; Flattened bony protrusion above eyes; Hypoplasia of supraorbital margins; Hypoplasia of the supraorbital ridges; Hypoplastic supraorbital ridges; Shallow orbital ridges; Shallow supraorbital ridge","HPO_Name__c":"Underdeveloped supraorbital ridges","HPO_Feature_Type__c":"Symptom"}},{"Provided_By__c":"ORPHA:2479","HPO_Frequency__c":"Occasional (5-29%)","Feature__r":{"HPO_Description__c":"Angle formed by the plane of the ear and the mastoid bone greater than the 97th centile for age (objective); or, outer edge of the helix more than 2 cm from the mastoid at the point of maximum distance (objective).","HPO_Feature_URL__c":"https://hpo.jax.org/browse/term/HP:0000411","HPO_Synonym__c":"Prominent ear; Prominent ears","HPO_Name__c":"Protruding ear","HPO_Feature_Type__c":"Symptom"}},{"Provided_By__c":"ORPHA:2479","HPO_Frequency__c":"Frequent (30-79%)","Feature__r":{"HPO_Description__c":"The palpebral fissure inclination is more than two standard deviations below the mean.","HPO_Feature_URL__c":"https://hpo.jax.org/browse/term/HP:0000494","HPO_Synonym__c":"Antimongoloid eye slant; Antimongoloid slant of palpebral fissures; Antimongoloid slanted palpebral fissures; Down slanting palpebral fissures; Down-slanted palpebral fissures; Down-slanting palpebral fissure; Down-slanting palpebral fissures; Downslanting palpebral fissure; Downslanting palpebral fissures; Downward slanted palpebral fissures; Downward slanting of the opening between the eyelids; Downward slanting palpebral fissures; Downward-slanting palpebral fissures; Palpebral fissures down-slanted","HPO_Name__c":"Downslanted palpebral fissures","HPO_Feature_Type__c":"Symptom"}},{"Provided_By__c":"ORPHA:2479","HPO_Frequency__c":"Frequent (30-79%)","Feature__r":{"HPO_Description__c":"Interpupillary distance more than 2 SD above the mean (alternatively, the appearance of an increased interpupillary distance or widely spaced eyes).","HPO_Feature_URL__c":"https://hpo.jax.org/browse/term/HP:0000316","HPO_Synonym__c":"Excessive orbital separation; Increased distance between eye sockets; Increased distance between eyes; Increased interpupillary distance; Ocular hypertelorism; Wide-set eyes; Widely spaced eyes; Widened interpupillary distance","HPO_Name__c":"Hypertelorism","HPO_Feature_Type__c":"Symptom"}},{"Provided_By__c":"ORPHA:2479","HPO_Frequency__c":"Occasional (5-29%)","Feature__r":{"HPO_Description__c":"Occipitofrontal (head) circumference greater than 97th centile compared to appropriate, age matched, sex-matched normal standards.
