Randy Rogers addresses daughter Rumer's death

Randy Rogers is trying to focus on the positive following daughter Rumer's death this month.

The 33-year-old Randy Rogers Band singer opened up about the infant's death in an interview newborn-daughter-dies-nonketotic-hyperglycinemia" target="_blank">with People published Thursday. Rumer Rain Rogers died at six days old from nonketotic hyperglycinemia June 9.

"She wouldn't eat and she wouldn't wake up," he recalled of his daughter. "They started running test after test and nothing was wrong with her. It was a six-day process. It was heart-wrenching and grueling not knowing what was wrong."

Nonketotic hyperglycinemia is a rare genetic disorder with no known cure. Rogers and wife Chelsea Cai Dowlearn learned they both carry the recessed gene, and will do in vitro fertilization after genetic testing if they decide to have another child.

"I'm just so happy that there are men and women so smart and passionate to be able to identify these things," he said. "Now because my daughter died and we now know we carry this gene, no one else in our family will have to have that happen to them and science is to thank for that."

Rogers and Dowlearn married in March 2013, and are also parents to five-year-old daughter Isabel and 21-month-old daughter River. The singer released Trouble with the Randy Rogers Band in April 2013, and collaborative record Hold My Beer, Vol. 1 with Wade Bowen in April.
