|Description:||This was the left hand of an infant (PHIL 15402-15407) who had been born with a chromosomal abnormality Trisomy 18, Trisomy E, and by the eponym, Edwards syndrome. It affects 1 in 5000 births, and is three time more common in girls than in boys. One of the symptoms associated with this genetic aberration is evidenced here in this clenched hand posture. Some of the other symptoms expressed by this child included mental delay, microcephaly, micrognathia, rounded or “rocker bottom” feet, and low-set ears.|
An infant suspected of possessing this chromosomal variation will display unusual fingerprint patterns, upon x-ray examination, a shortened breast bone, or sternum, and chromosomal examination will reveal trisomy, partial trisomy or a translocation phenomenon of chromosome 18.
