Local, hypoplastic type of amelogenesis imperfecta: a clinical, genetic, radiological and dermatoglyphic study.

A patient and her family members showing X-linked dominant form local, hypoplastic type of amelogenesis imperfecta (AI) were investigated from view-point of their teeth, clinical, genetic, radiological and particularly dermatoglyphic findings. It was suggested that it might be a close relationship between the intra-uterine development of both AI and unusual dermatoglyphs originated from the same layer, ectoderm and an X-linked dominant gene could determine both abnormal teeth and unusual dermatoglyphic characteristics in questions.

Congenital hypodontia: a pedigree and dermatoglyphic study.

The dermatoglyphs and the pedigrees of 11 male and 10 female, a total of 21 patients with congenital hypodontia (CH) were investigated. The dermatoglyphics of the patients were compared with those of 250 male and 250 female control cases. There were more arches on the finger-tips of the patients with absence of the lateral incisors, absence of the second premolars and a total patients with CH. The patients with absence of the lateral incisors had more palmar ll and plantar lll loops and p triradii. The patients with absence of the second premolars had more H and H loops, P triradii and plantar ll loops. A total patients with CH had more palmar ll and plantar lll, IV loops and p and z triradii. The pedigrees of the patients with both absence of the lateral incisors and the second premolars showed that the inheritance patterns of both conditions would seem autosomal recessive.

Bilateral absence of maxillary and mandibular second premolars: a clinical, genetic and dermatoglyphic study.

In the report presented here the mode of inheritance pattern of absence of maxillary and mandibular second premolars will be investigated by pedigree analyses and dermatoglyphic studies of a patient who showed the trait and his family members. An 11-year-old male patient with caries with bilateral absence of maxillary and mandibular second premolars was observed. Most of the dermatoglyphic traits observed in the patient were also found in the father and the sister of the patient.

A genetic and dermatoglyphic study on periodontitis.

Periodontal diseases encompass a wide range of disease manifestations and processes from the mildest inflammation of gingiva to the most advanced destructive periodontitis with loss of attachment, bone tissue and teeth. No entirely satisfactory identification and classification exist in periodontitis especially for high risk early onset periodontitis (EOP) cases, because of insufficient knowledge about the aetiological and host factors and their overlapping clinical and laboratory features. In this study, the dermatoglyphics, which is a genetic test method, suggesting the modes of inheritances of hereditary diseases, was performed on 36 EOP and 20 adult periodontitis (AP) patients and 20 periodontally healthy individuals. The diagnostic value of this genetic test method, which is the study of the quantitative and qualitative characteristics of patterns of ridged skin, and the role of heredity on periodontal diseases are discussed.

Dermatoglyphic study in children with phenylketonuria.

Dermatoglyphic findings in 19 patients with phenylketonuria (11 male and 8 female), 39 of their relatives (18 female and 21 male) and 500 controls (TRC) were not statistically significant among the three groups studied. There was no definite relationship between the phenylketonuric gene and the dermatoglyphic patterns. The parents of half the phenylketonuria cases are not consanguineous; thus the phenylketonuria gene may be more frequent in Turkey than other European countries.

Dermatoglyphic findings in Rubinstein-Taybi syndrome.

The dermatoglyphics of seven patients with Rubinstein-Taybi syndrome and their seventeen family members were compared with those of 250 male and 250 female controls. The most striking dermatoglyphic findings of the patients were the increased frequency of arches, decreased frequency of ulnar loops and reduced ridge-counts on the finger-tips, particularly on the thumbs, lower a-b ridge-counts, increased frequency of I, Ir, II loops, e, f, and t'' triradii, decreased frequency of H loops and tb triradii on the palms, increased frequency of If loops, decreased frequency of I loops, f and p triradii on the soles. The relatives of the patients had more radial loops on the finger-tips, I and Hr loops and t' triradii on the palms, II, III, loops, f and z triradii on the soles.

Aglossia-adactylia syndrome (special emphasis on the inheritance pattern).

Three cases, one with aglossia-adactylia and two with aglossia, are presented, all of whom were born to consanguineous families. Although none of the cases had similarly affected sibs, the possibility of the autosomal recessive mode of inheritance might be taken into account in this syndrome. The dermatoglyphic findings in one previously reported patient showed great similarity to those of one of our cases.

Hereditary index finger polydactyly: phenotypic, radiological, dermatoglyphic, and genetic findings in a large family.

Index finger polydactyly in a Turkish family is reported. The transmission of the malformation fits the pattern of regular autosomal dominant inheritance. Some of the affected individuals had one or two phalanges on their first digits, but all had triphalangeal second fingers. Subjects with polydactyly had very interesting dermatoglyphs, such as an extra a triradius under the super-numerary index finger, the proximal radiant of this triradius (an extra A-line) ending on the radial border of the hand, and arch tibials in the hallucal areas. The carpal bones, beginning with os multangulum majus, or alternatively with the extra one were articulated with two metacarpals. A similar finding was found in the feet.
