SOFT’s Professional Literature, Growth Charts & Surgery Information

Growth Charts, Surgeries & Literature

Children with trisomy 18 or 13 do not follow the standard infant and child growth patterns. These children are smaller at birth and grow more slowly than other children, especially those with trisomy 18. SOFT provides the only known Growth Curves for trisomy 18 and 13 and we suggest they be downloaded for use with affected children.

Reports of over 3,000 parent-reported surgeries or procedures have been collected into a Surgery Registry and compiled into surgery tables made available on this website.

SOFT’s surgery registry is helpful for families seeking another family whose child experienced the same surgery or for finding a trisomy-friendly surgeon. A number of researchers have utilized the surgery registry’s data for SOFT-approved studies.

Slowly but surely, during three decades of existence, SOFT has compiled a substantial library of professional literature about trisomy 18 and 13 which we are delighted to share with you below!

Also, see SOFT’s video channel for medical videos. It’s found under the “Resources” menu tab.

Trisomy Facts

Genes are the blueprint for our bodies. Almost every cell in the body has a copy of the blueprint, stored inside a sac called the nucleus. Genes are beaded along chromosomes, which are tightly bundled strands of the chemical substance deoxyribonucleic acid (DNA). Humans usually have 23 pairs of chromosomes, with two sex chromosomes that decide gender and 44 chromosomes that dictate other factors, such as growth and function.

A chromosome disorder is caused by an alteration in the number or genetic structure of chromosomes. Trisomy (‘three bodies’) means the affected person has 47 chromosomes instead of 46. Down syndrome, Edward syndrome and Patau syndrome are the most common forms of trisomy. Children affected by trisomy usually have a range of birth defects, including delayed development and intellectual disabilities.
