Focal facial dermal dysplasia type I (FFDD1), also known as Brauer syndrome, is a focal facial dysplasia with characteristics of congenital bitemporal cutis aplasia. The bitemporal rarely unilateral hypoplastic scar-like lesions in FFDD, resembling forceps marks, are usually the only manifestations of FFDD1. Most patients usually have normal intelligence. Transmitted in an autosomal dominant manner with full penetrance. | Is a | True | Focal facial dermal dysplasias (FFDD) are rare ectodermal dysplasias, characterized by congenital bitemporal (resembling forceps marks) or preauricular scar-like lesions associated with additional facial and or systematic manifestations. 4 types of FFDD are described.

Focal facial dermal dysplasia type II (FFDD2) is a focal facial dermal dysplasia with characteristics of congenital bitemporal scar-like depressions with additional facial dysmorphic features. Cardiac and genital or urinary abnormalities have been rarely noted. Developmental delay, severe intellectual disability, behavioural problems, and learning difficulties may be observed. Transmitted in an autosomal dominant manner with variable expressivity and incomplete penetrance. | Is a | True | Focal facial dermal dysplasias (FFDD) are rare ectodermal dysplasias, characterized by congenital bitemporal (resembling forceps marks) or preauricular scar-like lesions associated with additional facial and or systematic manifestations. 4 types of FFDD are described.

Focal facial dermal dysplasia type III (FFDD3) is a rare focal facial dermal dysplasia with primary characteristics of congenital bitemporal scar-like depressions and a typical but variable facial dysmorphism. Caused by homozygous mutations in the TWIST2 gene, which encodes a bHLH transcription factor involved in dermal facial development in mammals. However, the majority of unrelated FFDD3 patients evaluated have had normal TWIST2 sequences, indicating the molecular genetic heterogeneity of the disorder. Many cases are sporadic. Inheritance is autosomal recessive for patients with TWIST2 mutations. | Is a | True | Focal facial dermal dysplasias (FFDD) are rare ectodermal dysplasias, characterized by congenital bitemporal (resembling forceps marks) or preauricular scar-like lesions associated with additional facial and or systematic manifestations. 4 types of FFDD are described.

Focal facial dermal dysplasia type IV (FFDD4) is a rare focal facial dysplasia with characteristics of congenital isolated preauricular and/or cheek blister scar-like lesions. Affected FFDD4 patients typically do not present with extra-cutaneous manifestations, although in a small number of cases, a hair collar sign (circumscription of the cutaneous lesion with terminal hairs), polyps on the buccal mucosa with a similar distribution pattern, and developmental delay have been reported. An autosomal recessive trait. | Is a | True | Focal facial dermal dysplasias (FFDD) are rare ectodermal dysplasias, characterized by congenital bitemporal (resembling forceps marks) or preauricular scar-like lesions associated with additional facial and or systematic manifestations. 4 types of FFDD are described.
