Abstract |
Split hand and split foot(SHSF) is a human developmental defect characterized by missing digits, fusion of remaining digits, and a deep median cleft resulting in a clawlike appearance of the hands and feets. SHSF is usually inherited in an autosomer dominant fashion. The incidence of SHSF is between 1/10,000 and 1/90,000. Thirteen cases of SHSF and chromosomal aberrations involving 7q21-22 have been described so far in the world. We experienced a case of typical tetramelic SHSF in neonate. Chromosome studies showed a pericentric inversion of chromosome 7:46,XY,inv(7) (p22q22).
Inspection of the extremities and chromosome studies in the parents were normal. |
Key Words:
SHSF; Chromosome 7; Pericentric inversion |
