DYRK1A-related intellectual disability syndrome

What it is

A rare genetic syndromic intellectual disability characterized by microcephaly, global developmental delay, mild to severe intellectual disability, impairment of speech, feeding problems, behavior problems (often autism spectrum disorder) and dysmorphic facial features (such as prominent ears, deep-set eyes, a short nose with a broad nasal tip, and retrognathia with a broad chin). Other, more variable manifestations include seizures, short stature, ocular anomalies, cardiac anomalies, urogenital anomalies and musculoskeletal defects.

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.

Genes reported in subtypes

Orphanet records this gene on 2 more specific entries under this disorder, not on this entry itself:

A well-studied disease is usually split into subtypes, and the gene is curated on whichever one the evidence belongs to. Open a subtype to see which gene goes with it.

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.
