National MPS Society Funds Two GGC Projects


GREENWOOD, SC  – The National MPS Society has awarded two grants to Greenwood Genetic Center scientists. Director
of Functional Studies, Heather Flanagan-Steet, PhD, and Director of GGC’s Biochemical
Genetics Laboratory, Tim Wood, PhD, will be working on separate two-year projects aimed at improving
the diagnosis and treatment for these rare disorders.
Mucopolysaccharidoses (MPS) and related disorders, as a group, affect approximately 1 in 25,000 individuals. The Society provides support resources for
families as well as funding for research into this group of disorders which can affect the health, development, quality of life and lifespan of affected
Flanagan-Steet has been awarded a $90,000 grant from the National MPS Society to continue her previous work on mucolipidosis II (ML II), a rare genetic
disorder that causes coarse facial features, significant skeletal and joint abnormalities, intellectual disability, and a significantly shortened life
Flanagan-Steet has previously identified the importance of enzymes known as cathepsins in the development of heart and skeletal abnormalities in patients
with ML II. Cardiac disease is the most common cause of death in children with ML II. Her current project utilizes an ML II zebrafish model to better
understand how these enzymes function in cardiac and skeletal development and test inhibitors as a potential treatment to improve symptoms for these
“We are proud to support the outstanding science presented by Dr. Flanagan-Steet for her proposal, ‘Cysteine Cathespins as Therapeutic Targets in Mucolipidosis.’
This syndrome does not have a viable treatment on the market today,” said Terri Klein, President and CEO, National MPS Society. “Children diagnosed
with ML suffer from a progressive syndrome with shortened lifespans. Science of this caliber brings hope to the entire patient community, who have
waited decades for research to move forward.”
Wood’s $30,000 award from the National MPS Society will focus on better characterizing genetic changes found in the gene for MPS I. His lab will perform
enzymatic and biochemical analysis of variants in the gene that causes MPS I to determine if those variants are benign or disease-causing.
“Newborn screening for MPS I has begun in many states, so infants can be identified early, an advance that has important implications for treatment,” said
Wood. “However, this testing is identifying many new variants that we aren’t sure if they are actually disease-causing. This leaves families concerned
and frustrated, not knowing if their child is affected or not.”
GGC has a long-standing interest in MPS disorders, providing clinical care, diagnostic testing and research for many of these rare conditions.

A Rare Beauty

The lobby of the JC Self Research Institute at GGC was transformed into a garden – of sorts. The art exhibit titled ‘Rare Roses’ consisted of 12 paintings that depict real roses with genetic variations. The series was created by Nicole Shannon, an artist from Greenville. Nicole was inspired by her son, who has a rare genetic disorder, and other individuals with genetic differences. Quinn, now 4, was born with a myriad of health issues and ...
