English

Subject field(s)

DEF

Small stria having the form of a star with three arms from which palmar creases diverge in three directions. It is usually unique and situated in the proximal region of the palm at the convergence of the crease systems of thenar, hypothenar and carpus. Its normal position is designated by t. It can be very distal, at the limit of the flexion creases i.e., in t" or in an intermediate position i.e., in t’.

CONT

(Duplication 10q and 10p Syndrome) Frequent dermatoglyphic findings include transverse palmar creases, high axial triradius, and an increased number of ulnar loops.

DEF

Petite strie en forme d'étoile à trois branches d'où divergent selon trois directions les crêtes palmaires.

Il peut être très distal, à la limite des plis de flexion, c'est-à-dire en t", ou bien en position intermédiaire, en t'.

DEF

Angle formed by the lines joining the axial triradius t with the subdigital triradii a and d.

CONT

(Down’s syndrome) Subsequently Penrose (1965) suggested that the increased frequency of wide atd angles (distal axial triradii) in the mothers of these patients indicated that 10 per cent of these mothers were mosaics and at least half with more than one affected child would also be mosaics.

DEF

L'angle formé par les lignes joignant le triradius axial t aux triradius sous-digitaux a et d.

CONT

Les dermatoglyphes pathologiques de la trisomie 21 : [...] triradius axial en position t" dans 80 % des cas, avec angle atd de Penrose supérieur à 56 %.
