What it is

Branchioskeletogenital syndrome is a rare multiple congenital anomalies/dysmorphic syndrome characterized by moderate intellectual disability, distinctive craniofacial features (including brachycephaly, facial asymmetry, marked hypertelorism, blepharochalasis, proptosis, a broad nose with concave nasal ridge and bulbous nasal tip, midface hypoplasia, bifid uvula or partial cleft palate, and prognathism), progressive dental anomalies (dentigerous cysts, radicular dentin dysplasia and early tooth loss), vertebral fusions (particularly of C2-C3), and hypospadias. Hearing loss is an additional observed feature.

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.

ICD-10 codes

Q87.8filed under a broader ICD-10 category — shared with 581 other rare diseases

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
