A 39 year old male with multiple dysmorphic features was found to have an unstable ring chromosome 7. Clinical findings are presented and compared with the other five reported cases of ring chromosome 7. The main characteristics found in patients with this chromosome constitution are prenatal onset growth deficiency, bone anomalies, pigmentary or vascular skin changes, and ocular and genital an...

Terminal osseous dysplasia with pigmentary defects (TODPD) is an X-linked dominant syndrome with distal limb anomalies, pigmentary skin defects, digital fibromas, and generalized bone involvement due to a recurrent mutation in the filamin A (FLNA) gene. We here report the mutation c.5217G>A in FLNA in three families with TODPD and we found possible germline and somatic mosaicism in two out of t...

Sixty-four people with pigmentary anomalies of the skin were examined in the Eastern Highlands of New Guinea. Thirty-one had a bronze-red skin colour which appears to be unique to New Guinea. Eighteen of the Red-skins had congenital nystagmus which was not associated with impairment of visual acuity. The fundi were normal. The pigmentary anomaly is recessively inherited, and the gene responsibl...

Phakomatosis Pigmentovascularis (PPV) is a rare cutaneous congenital malformation syndrome, defined as simultaneous occurrence of congenital cutaneous vascular and pigmentary anomalies. As most of the reported cases are from Far East countries, especially Japan, we reported a case of PPV type IIa in an Iranian patient. This case was unusual because of the coexistence of unilateral extensive por...

Patients with Tietz syndrome have congenital profound deafness and generalised hypopigmentation, inherited in a fully penetrant autosomal dominant fashion. The pigmentary features and complete penetrance make this syndrome distinct among syndromes with pigmentary anomalies and deafness, which characteristically have patchy depigmentation and variable penetrance. Only one family has been reporte...

Tetraploid-diploid mosaicism in humans is exceedingly rare. We present an 11-year-old boy with tetraploid-diploid mosaicism and coexistent hair hypopigmentation with skin hypo- and hyperpigmentation. This case expands the current literature as we are not aware of previous documentation of this unique combination of pigmentary anomalies.

This paper describes a 7-year-old girl with trichodysplasia, normal teeth, onychogryposis, hypohidrosis, psychomotor and growth retardation, dry and warm skin with follicular hyperkeratosis, pigmentary disturbances (hyper- and hypochromic spots), bilateral nuclear cataract, dermatoglyphic anomalies, and other signs. This condition is considered a new form of ectodermal dysplasia.
