DYSMORPHOLOGY – CLINICAL PROTOTYPE
DOWN SYNDROME (DS)

Thalidomide embryopathy was a fundamental public health disaster that demonstrated the importance of Medical Teratology and lead to laws mandating that medications are safe for the unborn (see UTIS – Ukrainian Teratology Information System). Thalidomide embryopathy mostly impacts developing limbs and ears – does not impact significantly cerebral development. One of the principles of teratology in contrast to toxicology is that teratogens have specific impacts on embryonic development (see Teratology Principles).
Part 1 (in English, 9 min.).
Part 2 (in English, 7 min.).
Cretinism – Prenatal Iodine/maternal thyroid deficiency
Iodine deficiency is a worldwide public health problem that can be prevented by fortification of salt. Likewise, fortification of flavor of folic acid can reduce at least by 50% the impact of neural tube defects (NTD) (see Prevention of Birth Defects; see Prevention of NTD in Ukraine – video 1, video 2).
Environmental factors and genetics, in this instance mountainous region, related to soil iodine deficiency, lack of fortified salt with iodine and family genotypes are determining etiologic factors. Not all family members will express cretinism. Note that all infants are screened for impacts of iodine deficiency (thyroxin) calling for early therapy to prevent mental deficits.

Alcohol – Fetal Alcohol Embryopathy, Fetopathy, Syndrome, Spectrum Disorders (9 parts)
Alcohol is an optional “social” teratogen (100% avoidable) and also a toxin. Alcohol is arguably the most common teratogen and a cause of preventable functional and structural developmental anomalies.
Fetal Alcohol Spectrum Disorders (FASD) and Developmental Outcomes – An eminent presentation (with English or Ukrainian slides, 31 min.).
FASD – Clinical diagnosis, care and prevention – World perspective – Authoritative video

Another major teratogen, mutagen, and carcinogen (oncogene). The main impacts on human population stem from Medical applications, atomic bomb explosions, the Lenin nuclear power plant explosion in Chornobyl, the nuclear plant explosion in Fukushima in Japan and numerous accidents in nuclear power plants across the world.

The family history along argues of abuse, cruelty, criminality, non-paternity …
Neurofibromatosis peripheral type I (NF-1)
Mutation of one of the largest human genes manifested in an autosomal dominant phenotype. The clinical spectrum is variable and the scope very wide. NF-1 is a high cancer risk condition with prenatal and postnatal manifestations progressive in nature. The penetrance is high but manifestations may be settle and late.
A fibro – chondro – skeletal – autosomal – dominant – disorder, one of the most common causes of disproportional short stature. The penetrance is high. The grease of short stature may be moderate or severe (variability). Connective tissue laxity in combination with disproportionally large head is dangerous particularly during and after birth (apnea, cord injury …). Most severe instances may be due to other genes mutations (achondrogenesis). Most de-novo mutations are of paternal origin and reflect the impact of aging (a Down syndrome, the association with maternal aging).

Male Turner Noonan
Illustrates the notion of phenocopy – similar array of concurrent dysmorphic signs and malformations reflecting impacts on pathogenesis by different causes (etiology). Turner syndrome in females often is due to anomalies of an X-chromosome.
Patau Syndrome (2 patients)
Strictly speaking, Patau syndrome describes a cluster of anomalies associated with trisomy 13. 13+ syndrome should be only applied to patient with proven trisomy 13. The main characteristic signs are those associated with holoprosencephaly (microphthalmia, midline facial clefts – see the galleries). Another two important points are: other causes result in similar syndromes and the syndromes are largely lethal (teratothanasia).
