The association between agnathia and holoprosencephaly is well documented (Pauli et al., 1981). Pauli et al. described two female sibs with agnathia and holoprosencephaly who were subsequently shown to carry an unbalanced 46, XX, der 18,t(6;18)(pter P24.1) karyotype (Pauli et al., 1983; Krassikoff and Sekhon, 1989). All other cases have been sporadic (Cohen, 1989). We present a recurrence of agnathia-holoprosencephaly in an unrelted European couple and postulate that this association may represent an autosomal recessive syndrome.

机译:无脑畸形和全脑畸形之间的关联是有据可查的(Pauli et al., 1981)。Pauli 等人描述了两个患有无脑畸形和全脑畸形的女性同胞,她们随后被证明携带不平衡的 46, XX, der 18,t(6;18)(pter P24.1)核型(Pauli等人,1983;Krassikoff 和 Sekhon,1989 年)。所有其他病例都是散发的(Cohen,1989)。我们提出了一对未有血缘关系的欧洲夫妇的无意识-全脑畸形复发,并假设这种关联可能代表常染色体隐性遗传综合征。
