Preferred Label : Trigonocephaly with short stature and developmental delay;
Type : Other, mainly phenotypes with suspected mendelian basis;
Alternative titles and symbols : SAMES; Say-meyer syndrome;
Description : Say and Meyer (1981) observed trigonocephaly in 3 males in 3 maternally related sibships,
consistent with X-linked recessive inheritance. Autosomal dominant inheritance with
low expressivity in women could not be excluded. The oldest of the 3, aged 30, was
162 cm tall and was moderately mentally retarded. The other 2, nephews of this man,
had a closed posterior fontanel, very small anterior fontanel, and a marked frontal
vertical ridge; narrow forehead; hypotelorism and marked retardation in weight, height,
head circumference, and psychomotor development. Normally the major sutures of the
cranial vault close between 28 and 32 years of age; the metopic suture closes much
earlier, usually during the second or third year of life. Say and Meyer (1981) found
no similar reported case and specifically distinguished the disorder from the trigonocephaly
with minor anomalies reported in mother and son by Hunter et al. (1976) and from the
Opitz trigonocephaly syndrome (211750). *FIELD* RF 1. Hunter, A. G. W.; Rudd, N. L.;
