Ruvalcaba syndrome



Ruvalcaba syndrome is an extremely rare malformation syndrome, described in less than 10 patients to date, characterized by microcephaly with characteristic facies (downslanting parpebral fissures, microstomia, beaked nose, narrow maxilla), very short stature, narrow thoracic cage with pectus carinatum, hypoplastic genitalia and skeletal anomalies (i.e. characteristic brachydactyly and osteochondritis of the spine) as well as intellectual and developmental delay.

Medical Term Other Names Description
Abnormality of the skeletal system Skeletal anomalies An abnormality of the skeletal system.
Narrow mouth Microstomia, Small oral aperture, Small mouth [more] Distance between the commissures of the mouth more than 2 SD below the mean. Alternatively, an apparently decreased width of the oral aperture (subjective).
Global developmental delay Psychomotor developmental delay, Psychomotor retardation, Developmental delay, Lack of psychomotor development, Cognitive delay, Delayed intellectual development, Delayed milestones, Psychomotor development deficiency, Developmental retardation, Motor and developmental delay, Developmental delay in early childhood, Retarded psychomotor development, Retarded mental development, Delayed cognitive development, Retarded development, Delayed developmental milestones, Delayed development, Psychomotor development failure, Mental and motor retardation, Psychomotor delay, Delayed psychomotor development [more] A delay in the achievement of motor or mental milestones in the domains of development of a child, including motor skills, speech and language, cognitive skills, and social and emotional skills. This term should only be used to describe children younger than five years of age.
Microcephaly small cranium, Decreased circumference of cranium, Small head, Small skull, Small head circumference, Reduced head circumference, Decreased size of cranium, Decreased size of skull, Abnormally small skull, Decreased size of head, Abnormally small cranium, small calvarium, Abnormally small head [more] Occipito-frontal (head) circumference (OFC) less than -3 standard deviations compared to appropriate, age matched, normal standards (Ross JJ, Frias JL 1977, PMID:9683597). Alternatively, decreased size of the cranium.
Brachydactyly Digits that appear disproportionately short compared to the hand/foot. The word brachydactyly is used here to describe a series distinct patterns of shortened digits (brachydactyly types A-E). This is the sense used here.
Convex nasal ridge Beaked nose, Polly beak nasal deformity, Hooked nose, Convex dorsum of nose, Convex nasal dorsum, Beaklike protrusion [more] Nasal ridge curving anteriorly to an imaginary line that connects the nasal root and tip. The nose appears often also prominent, and the columella low.
Narrow maxilla Transverse hypoplasia of maxilla, Narrow upper jaw bones, Decreased width of maxilla, Decreased width of upper jaw bones, Decreased transverse dimension of maxilla, Transverse maxillary deficiency, Decreased breadth of upper jaw bones [more]
Short stature Decreased body height, Height less than 3rd percentile, Small stature, Stature below 3rd percentile [more] A height below that which is expected according to age and gender norms. Although there is no universally accepted definition of short stature, many refer to "short stature" as height more than 2 standard deviations below the mean for age and gender (or below the 3rd percentile for age and gender dependent norms).
Pectus carinatum Pigeon chest A deformity of the chest caused by overgrowth of the ribs and characterized by protrusion of the sternum.
