Shared Psychotic Disorder

Shared psychotic disorder, characterized by shared delusion among two or more subjects (termed “Folie à deux,” “trois,” etc.), is often associated with strong religious beliefs or social isolation, factors creating strong psychological sympathy. Recently, we treated a rare familial case of “Folie à quatre” in central Tokyo without such influences. The proband was a schizophrenia patient and younger brother within monozygotic twins. Positive symptoms were “transmitted” to remaining family members, his elder brother, mother, and father father, in a relatively short period of three months. Although the pathophysiology of these positive symptoms (delusions and hallucinations) remains unclear, the transmission pattern suggests the primacy of social and environmental factors (and/or their interaction), while genetics appeared less influential in this “Folie à famille.” Although undiagnosed psychoses in the whole family cannot be excluded, they did not share the other negative schizophrenia symptoms of the proband. A strong familial connection appeared to be the most important factor for the common delusion and hallucination.

A pair of autistic monozygotic twins were assessed on relevant portions of the Geddes Psychomotor Inventory. Over-all motor development of the 3-yr., 6-mo. old twins was similar and considered a partial consequence of the same genotype and comparable environmental experiences from birth. The twins exhibited poor or unsuccessful performance on tasks requiring abilities in language, communication, and appropriate relationships to objects; superior performance on specific fine manual motor skills, walking balance board, and climbing; at-age performance on tasks which were considered measures of patterned gross movement, balance, postural maintenance, and spatial orientation; and few typical autistic motor characteristics.

Variable Penetrance

A case study of monozygotic twins with bilateral calcaneonavicular coalitions is presented. With the frequency of tarsal coalitions being approximately 1% to 2% and the frequency of monozygotic twins being 0.4%, it is a rare but predictable finding to see monozygotic twins with tarsal coalitions. This sheds additional light on the etiology of tarsal coalition that historically has been believed to be a defect in mesenchymal differentiation with indications of a genetic component. Despite the limited number of subjects used for various studies, tarsal coalitions have been considered to be an autosomal dominant defect with variable penetrance. In fact, inheritance of tarsal coalitions is more complicated than simple mendelian inheritance patterns and is likely to be a single error in a polygenic system. Because of this inheritance pattern, it is important to consider evaluating siblings and close family members of patients diagnosed with a tarsal coalition.
