Nancy McConnell, wife of Mike McConnell, and
their daughter, Morgan, 17. Morgan was born with
the generic disorder LCHAD.

An ordinary December morning
in 1996 turned into a nightmare for Mike McConnell and his
wife, Nancy. McConnell sat at his desk in his Atlanta law
office when he got a frantic phone call from Nancy. She
feared their 9-month-old daughter, Morgan, was dead.
"When my
wife tried to wake her in the morning, her eyes were rolled
back in her head," he said.
The couple
rushed Morgan to Children's Healthcare of Atlanta at
Scottish Rite where she spent two weeks in intensive care as
baffled doctors tried to diagnose her condition. Finally,
they got an answer: Morgan had a genetic disorder known as
LCHAD -- long-chain L-3 hydroxyacyl-CoA dehydrogenase
deficiency -- that prevented her body from breaking down
fats. Children with LCHAD can grow and develop normally, but
only if parents know they need to eat a special diet.
"The
difference between life and death is so simple if you know
your child has LCHAD," McConnell said. "But without a test,
you would never know your child had this disorder. They seem
perfectly normal."
Newborn
screening, a series of genetic tests on a blood sample taken
at birth, can make a world of difference for children like
Morgan. It allows health officials to identify babies with
inherited conditions and work with parents to give them
special care before certain foods, viruses or other health
problems cause death or irreversible damage to their bodies
and brains.
The CDC has
called newborn screening one of the top 10 greatest public
health achievements of the 21st century. Today, all 50
states screen every newborn for at least 26 genetic
disorders, such as PKU, sickle cell anemia and cystic
fibrosis, allowing many children to live healthy lives while
managing their conditions. The process has prevented
thousands of deaths and saved thousands more from severe,
debilitating conditions.
Georgia's
newborn screening program is no exception. In 2010 and 2011,
the state evaluated more than 246,000 infants, identified
28,157 infants at risk for a debilitating disorder and
confirmed 548 infants had one of the 28 conditions.
"This is
truly a public health success that every baby born is tested
for dozens of these conditions," said Arthur Hagar, Ph.D.,
director of newborn screening for the Georgia Department of
Public Health (DPH). "But most parents don't even realize
that the tests have been done for their children."
For all
Georgia infants, the work happens at the DPH laboratory in
Decatur. When a baby is born, the hospital takes blood from
a heel stick, puts it on a special paper and sends it to DPH
scientists at the lab, where the sample is analyzed and any
abnormalities are recorded. The results are reported to the
baby's physician within two or three days. Those rapid test
results allow doctors and parents to quickly determine that
a child needs special care, such as eating a certain diet,
to save their lives.
Hagar said
the newborn screening program is about more than lab
results. The program connects parents with resources they
need to manage their children's conditions, such as genetic
counselors and specialized doctors.
"It's not
just a lab test. We have a whole system in place," Hagar
said. "The test in the lab is very important, but it's only
one piece."
The system
was not always so robust. Georgia's newborn screening
program began in 1968 with a single test for phenylketonuria
(PKU), which had been developed a few years earlier. The
program slowly expanded to include other conditions, but
like many states' screening programs, limited technology,
funding and follow-up capacity prevented health officials
from testing babies for more abnormalities. When the
McConnells' daughter was born in 1996, Georgia's newborn
screening program screened for just nine conditions and
LCHAD was not one of them. As a result, Morgan's parents had
no idea of Morgan's condition until she nearly died from it.
After that
experience, McConnell became an outspoken advocate for
bulking up the state's newborn screening program. He served
on the Georgia Newborn Screening Program Advisory Committee
for 10 years, three of them as its chair, and worked with
the March of Dimes when the organization donated a mass
spectrometer to the state, greatly enhancing its newborn
screening capabilities. McConnell was also present the day
the Georgia legislature passed a bill mandating all newborns
be screened for 28 disorders, including LCHAD, in 2007.
"That was
one of my happier days," he said. "These children's lives
can be saved if you just know they have these conditions.
And that's what newborn screening allows parents to do."
This year,
the Association of Public Health Laboratories is celebrating
50 years of newborn screening in the U.S. The DPH lab will
join the organization in hosting the joint meeting of the
Newborn Screening and Genetic Testing Symposium and the
International Society for Neonatal Screening May 5-10 in
Atlanta. DPH employees at 2 Peachtree also will have the
chance to learn more about the history of newborn screening
with a traveling exhibit that will be on display in the
lobby from April 29 - May 9.
