Abstract
A case of ring 17 chromosome in a 5 mo. old male infant is investigated and compared with 5 previously reported cases. The findings commonly observed in these patients include mental and motor retardation, seizures, short stature, muscular hypotonia and microcephaly. Dermatoglyphic studies showed an increased number of ulnar loops. Bilateral transverse hypothenar creases were noted. Two of the cases had unspecified genital abnormalities. The variation in clinical findings among these patients may be due to a difference in the breakpoints on chromosome 17.
