Abstract
Two cases of Smith-Lemli-Opitz syndrome type II are presented. During the late stages of both pregnancies maternal oestriol levels were unrecordable and there was evidence of suppression of maternal adrenal function. We speculate on the existence of a primary defect in the fetal adrenals.

Abstract
Using reverse genetics, a candidate for the sex determining gene from the Y chromosome has recently been cloned. We have used a DNA probe from this gene to assess the presence of this crucial region of the Y chromosome in patients with sexual ambiguity or gonadal dysgenesis. The DNA from 3 cases of gonadal dysgenesis, one complicated by somatic anomalies and mental retardation, reacted normally with this putative sex determining gene. A patient having a small phallus and pseudovaginal, perineoscrotal hypospadias (PPSH) also had normal Y chromosomal DNA. We hypothesize that the defect in sex determination in all 4 cases is most probably subsequent to the primary sex determining switch.

Abstract
A diagnosis of Smith-Lemli-Opitz syndrome was made shortly after birth in a small-for-dates infant, on the basis of a characteristic face, penoscrotal hypospadias, bilateral postaxial hexadactyly, and bilateral syndactyly of toes 2-3. The clinical course was marked by failure to thrive, severe delay, refractory myoclonic jerks beginning at age 2 months, and increasing hepatosplenomegaly. He developed corneal clouding and increased gingival hypertrophy and died at age 18 weeks. Autopsy disclosed widespread storage of mucopolysaccharides and lipids within the macrophages and, to a lesser extent, parenchymal cells, of all organ systems. There was extensive demyelination of the cerebral white matter, and dystrophic calcification in the cerebrum, cerebellum, and brainstem. There was no evidence of primary neuronal involvement in the storage. Although the chance concurrence of 2 uncommon diseases is rare, a causal link between the clinical anomalies and the storage disorder cannot be argued convincingly on the basis of one case. Careful pathologic studies of other children who die with clinical signs compatible with Smith-Lemli-Opitz syndrome are indicated.

Abstract
We describe a 46,XY newborn infant with Smith-Lemli-Opitz syndrome (SLOS) with multiple congenital anomalies including female external genitalia, a testis palpable in each labium majus, a cone-shaped cervix, and normal vagina. Additional anomalies included cleft palate, total anomalous pulmonary venous return, and striking limb defects (ectrodactyly of the left upper limb, radial aplasia, and monodactyly of the right upper limb). To our knowledge, this is the first report of SLOS associated with limb deficiency and the third associated with total anomalous pulmonary venous return. Our patient demonstrates that limb deficiencies may be a rare component manifestation in this syndrome of multiple congenital anomalies.

Abstract
Three children are described from two sibships. They share infantile ataxia with hypo/aplastic vermis, hepatic fibrocirrhosis, slender-shaped skeleton, peculiar face, and moderate mental retardation. One of them had a kidney biopsy that showed mild interstitial fibrosis and amyloid deposit, but had no functional impairment. Another suffered moderate proximal tubular acidosis. Two children had unilateral or bilateral choroidal coloboma. This pattern of defects is consistent with a syndrome previously reported in two other sibships. The acronym COACH (Cerebellar vermis hypo/aplasia, Oligophrenia, congenital Ataxia, Coloboma, Hepatic fibrocirrhosis) is suggested.

Abstract
A newborn male infant was found to have an unusual pattern of congenital anomalies associated with an apparently balanced de novo reciprocal translocation: 46,XY,t(1;2)(p22;q22). The infant had a previously apparently undescribed multiple congenital anomalies and mental retardation syndrome.
