We report a 19 year-old patient carrying a terminal 20p microdeletion. She
displayed clinical features resembling those of two other previously described
patients. We suggest that a specific phenotype can be associated with this
chromosomal anomaly. Mental retardation, epilepsy, and dysmorphic signs including
low-set ears and overfolded helices seem highly characteristic of this syndrome
and may define major diagnostic criteria of a recognizable phenotype. Delayed
closure of fontanella, delayed permanent teeth eruption, visual disturbances,
prominent ear lobes, prominent nasal root and ridge, thin upper lip and
brachydactyly may represent inconstant minor criteria.
