Also called Distal deletion 19p13.3 · Distal monosomy 19p13.3 · Telomeric deletion 19p
What it is
Distal monosomy 19p13.3 is a rare chromosomal anomaly associated with a wide range of phenotypic features depending on the size of the deletion. It may present with intrauterine growth retardation, failure to thrive, global developmental delay, dysmorphic features (such as broad forehead, midface retrusion, broad nasal bridge, micrognathia, smooth philtrum, low-set, dysplastic ears), congenital anomalies (such as atrial septal defect, gastrointestinal anomalies, renal and urogenital malformations, agenesis of the corpus callosum) and other clinical features (such as hearing loss, visual impairment and immune dysregulation).

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.
