7p22.1 microduplication syndrome

What it is

7p22.1 microduplication syndrome is a rare chromosomal anomaly syndrome, resulting from a partial interstitial microduplication of the short arm of chromosome 7, characterized by intellectual disability, psychomotor and speech delays, craniofacial dysmorphism (including macrocephaly, frontal bossing, hypertelorism, abnormally slanted palpebral fissures, anteverted nares, low-set ears, microretrognathia) and cryptorchidia. Cardiac (e.g., patent foramen ovale and atrial septal defect), as well as renal, skeletal and ocular abnormalities may also be associated.

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.
