Oculocutaneous albinism (OCA) is an autosomal recessive disorder characterized by hypopigmentation in eyes, hair and skin, accompanied with vision loss. Currently, six genes have been identified as causative genes for non-syndromic OCA (OCA-1∼4, 6, 7), and ten genes for syndromic OCA (HPS-1-9, CHS-1). Genetic counseling of 51 Chinese OCA families (39 OCA-1 with mutations in the TYR gene, 6 OCA-2 with mutations in the OCA2 gene, 4 OCA-4 with mutations in the SLC45A2 gene, 1 HPS-1 (Hermansky-Pudlak syndrome-1) with mutation in the HPS1 gene, and 1 mixed OCA-1 and OCA-4) led us to perform the prenatal genetic testing of OCA using amniotic fluid cells through the implementation of our optimized strategy.

Obesity is one of the largest health problems facing the world today. Although twin and family studies suggest about two-thirds of obesity is caused by genetic factors, only a small fraction of this variance has been unraveled. There are still large numbers of genes to be identified that cause variations in body fatness and the associated diseases encompassed in the metabolic syndrome (MetS).

Oculocutaneous albinism (OCA) is a heterogeneous and autosomal recessive disorder with hypopigmentation in the eye, hair, and skin color. Four genes, TYR, OCA2, TYRP1, and SLC45A2, have been identified as causative genes for nonsyndromic OCA1-4, respectively. The genetic identity of OCA5 locus on 4q24 is unknown.

A case of hereditary benign telangiectasia without family history was reported. A 39-year-old woman presented with small and tiny telangiectases on the face, neck, upper trunk and forearms at birth. The numbers and sizes of the lesions increased gradually and she had no hemorrhagic diathesis and systemic diseases.
