Clinicians who practice dysmorphology well have certain personality traits that aid them in their pursuit of a diagnosis. Dysmorphology is at its apex of clinical maturation, but scientific discoveries and technology have begun to explain how and why malformations arise and why syndromes vary. Nevertheless, expertise in dysmorphology remains a clinical skill attainable by all who desire it. This visual diagnostic modality is inexpensive and often quick.

This study investigated the penetrance of the FMR-1 gene in cytogenetically negative but DNA-positive heterozygotes with a premutation (cytosine guanine guanine [CGG] amplification in the 50 to 200 repeat range), compared with carriers with a full mutation (> 200 CGG repeats) and control subjects. One hundred thirty-nine women with normal IQs between the ages of 18 and 45 years were studied. All underwent cytogenetic and DNA testing to determine their fragile X carrier status. A medical history-taking and a physical examination, including selected anthropometric measurements, were performed. Results indicate that the FMR-1 mutation mildly affects the physical phenotype of individuals even in the premutation state, although less dramatically than more affected heterozygotes. Carriers with a premutation differed significantly from control subjects in overall physical index score and in the anthropometric measure of ear prominence.

It is estimated that as many as 3000 hyperphenylalaninemic females may be at risk for producing these fetal abnormalities. To examine this problem, the North American Maternal PKU Collaborative Study has been developed to evaluate the efficacy of a phenylalanine-restricted diet in reducing fetal morbidity. Preliminary findings indicate that phenylalanine restriction should begin before conception for females with PKU planning a pregnancy. Dietary control should maintain maternal blood phenylalanine levels between 120 and 360 mumol/L and should provide adequate energy, protein, vitamin, and mineral intake.
