Spastic paraplegia, optic atrophy, microcephaly with normal intelligence, and XY sex reversal: a new autosomal recessive syndrome?

Two female sibs of first cousin Iranian parents were found to have the syndrome of spastic paraplegia, optic atrophy with poor vision, microcephaly, and normal cognitive development. Karyotype analysis showed a normal female constitution in one and a male constitution (46,XY) in the other. The XY female showed normal female external genitalia, normal uterus and tubes, and streak gonads.

We report on an Arab boy with Keutel syndrome and cerebral calcifications identified at 15 years while investigating a seizure disorder. The parents are phenotypically normal first cousins.

Genetic referrals of Middle Eastern origin in a western city: inbreeding and disease profile.

Inbreeding or consanguineous marriage is a common traditional practice in Middle Eastern cultures. Studies from various countries and communities of this region showed that the frequencies range from 20% to greater than 70%. Inbreeding is known to have adverse effects on morbidity and mortality, in particular with respect to autosomal recessive disorders.

Neonatal facial and cry responses to invasive and non-invasive procedures.

Evaluation of pain in neonates is difficult due to their limited means of communication. The aim was to determine whether behavioural reactions of cry and facial activity provoked by an invasive procedure could be discriminated from responses to non-invasive tactile events. Thirty-six healthy full-term infants (mean age 2.
