Definition
Trigonocephaly-short stature-developmental delay syndrome is characterised by short stature, trigonocephaly and developmental delay. It has been described in three males. Moderate intellectual deficit was reported in one of the males and the other two patients displayed psychomotor retardation. X-linked transmission has been suggested but autosomal recessive inheritance can not be ruled out.

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.
