SLC12A2-related developmental delay-intellectual disability-sensorineural deafness syndrome

What it is

A rare genetic, syndromic intellectual disability syndrome characterized by mild to severe global developmental delay and intellectual disability, delayed or absent speech and walking, and bilateral sensorineural deafness. Severity of the symptoms are variable. Patients may manifest with profound hypotonia, severe feeding difficulties and secretory dysfuntion. Autistic features, spasticity, mild and non-specific dysmorphic features and cardiac defects were reported in some patients.

Disease

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.

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.
