Subject diagnosed with Mosaic Turner syndrome and trisomy 7q at approximately 1 year of age; 20 week ultrasound revealed enlarged ventricles, mother had premature rupture of membranes at 32 weeks, subject was born at 34 weeks with numerous neonatal problems: temperature dysregulation, initial hypoglycemia, shallow breathing, hyperbilirubinemia requiring phototherapy and significant feeding problems requiring NG tube; discharged at 23 days old; Dysmorphic features include: very fair translucent skin; easily visible vasculature; macrocephaly; high broad forehead; bitemporal narrowing; bony protuberance over the occiput; underdeveloped orbital ridges; delayed closure of anterior fontanel; synophyrs-central brow lighter in pigmentation; hypertelorism; upturned nose tip; low set ears; under bite; high arched palate; delayed dentition; bifid uvula; small sublingual frenulum; neck mildly short; pectus excavatum-chest relatively narrow; palpable spleen tip about 1 cm below left costal margin; significant scoliosis (thoraco-lumbar); prominence of the right paraspinal region when bending forward in sitting position; shallow sacral dimple; downy pubic hair; hyperextension of ankles and elbows; left hand clinodactyly with 1 palmar crease; right hand clinodactyly with 1 palmar crease; right leg bulkier than left; prominent heels with pes planus; broad first toes; small gap between the 4th and 5th toes; developmental delay; motor delay; hyptonia; arching noted at 4 months; flaps hands when excited; clenches fists; protrudes tongue at rest; tendency to point toes when supine, hyperextension of ankles; head lag; varied muscle tone; long history of constipation; history of serous otitis media; eustachian tube dysfunction; snoring; chronic rhinitis; tonsillar and adenoid disturbance; history of intermittent “heavy breathing” while sleeping; mouth breathing; abnormal female karyotype: 46,X,der(X)t(X;7)(24).ish 7q11.23 (ELN-)[24]/45,X[6]; XIST gene determined to be on the derivative X chromosome by XIST-containing BAC FISH probe; normal MRI; normal abdominal ultrasound, pelvic ultrasound and renal ultrasound; head x-ray revealed enlargement of the adenoidal soft tissues; echocardiogram revealed very mild prolapse of the anterior leaflet of the mitral valve and a prominence of the septum in the sub-aortic region with no LV outflow obstruction; assistive devices includes orthotics (DAFO’s); treatments include early intervention, physical, speech, and occupational therapy; communicates using sign language.
