Cause of WS | 97% have deletion of ELN, gene for elastin, on chromosome 7--there is a 50% chance of parents trasmitting this mutation to offspring |
Physical features of WS | elfin-like facial features, short up-turned nose, long philtrum, broad forehead, full cheeks, puffiness under eyes, prominent earlobes |
Prevalence of WS | 1 in 20,000 people, equally prevalent in males and females, all races and cultures, equally likely to be transmitted by father or mother |
Medical features of WS | SVAS (supravalvular aortic stynosis, narrowing of aortic artery), hypercalcemia (too much calcium in blood), cardiac disease, hypertension, coordination difficulties, short stature, strabismus, hyperacusis, chronic otitis media |
Strengths of WS | auditory short-term memory, facial recognition and memory, theory of mind, musicality |
Weaknesses of WS | visual-spatial construction, perceptual planning, fine motor control |
Linguistic features of WS | delays in language acquisition in young children, but adolescents and adults may show remarkable language skills |
Linguistic strengths of WS | lexicon/vocab, auditory short-term memory, syntax |
Linguistic weaknesses of WS | delay of first words, prelinguistic skills, pragmatics |
Adaptive living abilities of WS | daily living skills show moderate delay (lower rhythmicity); may be socially uninhibited--can lead to exploitation, difficulty making and keeping friends (talk too much, get caught up in drama), worriers (anxiety, obsessions, preoccupations, fears) |
Diagnosis of WS | based on SVAS, developmental delay, infantile hypercalcemia, facial appearance, cognitive impairment, and overly friendly personality |
