Pseudoaminopterin syndrome

What it is

Pseudoaminopterin syndrome is a developmental anomalies syndrome that resembles the aminopterin embryopathy without history of fetal exposure to aminopterin. It is characterized by skull (craniosynostosis and poorly mineralized cranial vault), dysmorphic (ocular hypertelorism, palpebral fissure anomalies, micrognathia cleft lip and/or high arched palate and small and low set/rotated ears) and limb (brachydactyly, syndactyly and clinodactyly) anomalies, associated with mild-to-moderate intellectual deficit and short stature.

Classified as

Malformation syndrome

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

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.
