North Dakota Mom Gives Birth to Twin Boys, and Only One Has Dwarfism

In a rare occurrence, only one of her twins was born with dwarfism.

— -- Twins Christian and Dalen Lawler were born healthy boys on Jan. 20. Except in a rare occurrence, Dalen has dwarfism. Christian does not.

"Dalen was born at 8:37 p.m. and Christian was born one minute later," mom Christy Lawler told ABC News today. "Both of them, perfectly healthy, went to the regular nursery. I was looking over them and I did notice Dalen’s hands were different from Christian's. They were short, compact, and chubby and I said 'you know, maybe you do have what they were saying.'"

Lawler, of Fargo, North Dakota, said that at 32 weeks pregnant a genetic doctor told the 26-year-old mom of three that one of her children could have achondroplasia, a common form of dwarfism that affects bone growth in humans.

But due to potential health risks, Lawler said she declined doctors' offers to perform amniotic tests that would reveal Dalen's diagnosis prior to birth.

On April 15, Lawler announced on Dalen's Facebook benefit page that he had been diagnosed with dwarfism.
