  "description": "Resource structure is based on UKCore-HeadCircumferenceMeasurements v1.0.0 which is not yet included in a balloted release. Added manually to prevent structure deviation and to support NHS Wales projects. Once available, the resource will be updated and derived from UK Core. A code from the SNOMED CT UK coding system for the measurement of head circumferences. Selected from the SNOMED CT UK coding system: \\\\n - DescendantOrSelfOf 363811000 | Head circumference measure (observable entity) \\\\n - MINUS   \\\\n - 1153594009 | Head circumference for age z-score (observable entity)  \\\\n - 70751000052109 | Head circumference of biological father (observable entity)  \\\\n - 70761000052107 | Head circumference of biological mother (observable entity)   \\\\n - DescendantOrSelfOf 170061009 | Child head circumference centile (observable entity)",
