Lactate is produced from pyruvate by lactate dehydrogenase during normal metabolism. The terms lactate and lactic acid are often used interchangeably but lactate (the component measured in blood) is strictly a weak base whereas lactic acid is the corresponding acid. Lactic acidosis is often used clinically to describe elevated lactate but should be reserved for cases where there is a corresponding acidosis (pH below 7.35).","HPO_Feature_URL__c":"https://hpo.jax.org/browse/term/HP:0002151","HPO_Synonym__c":"Increased blood lactate; Increased serum lactate","HPO_Name__c":"Increased circulating lactate concentration","HPO_Feature_Type__c":"Lab"}},{"Provided_By__c":"OMIM:615471","Feature__r":{"HPO_Description__c":"An abnormal configuration of the lower lip such that it is turned outward i.e., everted, with the Inner aspect of the lower lip vermilion (normally opposing the teeth) being visible in a frontal view.","HPO_Feature_URL__c":"https://hpo.jax.org/browse/term/HP:0000232","HPO_Synonym__c":"Drooping lower lip; Eclabium of lower lip; Everted lower lip; Everted prominent lower lip; Outward turned lower lip","HPO_Name__c":"Everted lower lip vermilion","HPO_Feature_Type__c":"Symptom"}},{"Provided_By__c":"OMIM:615471","HPO_Frequency__c":"Frequent (30-79%)","Feature__r":{"HPO_Description__c":"An increase in size of the ventricular system of the brain.","HPO_Feature_URL__c":"https://hpo.jax.org/browse/term/HP:0002119","HPO_Synonym__c":"Cerebral ventricular dilatation; Dilated cerebral ventricle; Dilated cerebral ventricles; Dilated ventricles; Enlarged cerebral ventricles; Enlarged ventricles; Enlarged ventricular system; Large cerebral ventricles and cisternae; Ventricular dilatation","HPO_Name__c":"Ventriculomegaly","Feature_System__c":"Nervous System","HPO_Feature_Type__c":"Symptom"}},{"Provided_By__c":"OMIM:615471","HPO_Frequency__c":"Occasional (5-29%)","Feature__r":{"HPO_Feature_URL__c":"https://hpo.jax.org/browse/term/HP:0007109","HPO_Name__c":"Periventricular cysts","Feature_System__c":"Nervous System","HPO_Feature_Type__c":"Symptom"}},{"Provided_By__c":"OMIM:615471","HPO_Frequency__c":"Very frequent (80-99%)","Feature__r":{"HPO_Description__c":"Upturning of the big toe (and sometimes fanning of the other toes) in response to stimulation of the sole of the foot.
