遺伝子 link to heart defect

A new genetic 発見 could one day help doctors save the lives of babies born with heart defects, say scientists.

A US team has linked 突然変異s in the 遺伝子 GATA4 to congenital heart defects - a 主要な 原因（となる） of death in newborn 幼児s.

It 熟考する／考慮するd the genetic make-up of a Texas family which 含むd 16 people with heart defects 加える a Japanese family which had eight members with heart defects.

The mutant 遺伝子 was 設立する in all family members with heart defects.

The team 嫌疑者，容疑者／疑うs the 遺伝子 interacts with a protein linked to heart problems. It 設立する that when part of the 遺伝子 was altered it did not interact with the protein.

This raised the hope of 存在 able to 停止（させる） the congenital 条件, which often stops the 塀で囲むs which separate the heart's four 議会s from forming 適切に.

Dr Deepak Srivastva, of Texas University, said: "We cannot change the fact that parents are going to pass on the 突然変異 but we might be able to develop a way to keep the 病気 from occurring."

The 熟考する／考慮する is published online by the 定期刊行物 Nature.

  • Hope of cure for muscle 病気

    Scientists believe they have discovered a way to 打ち勝つ the genetic defect that 原因（となる）s the most serious form of muscular dystrophy.

    About one in 3,500 baby boys is born in the UK each year with the Duchenne form of the 病気. Most die before they are 30.

    Now the 医療の 研究 会議 has used tiny pieces of genetic 構成要素 to 'patch over' the genetic defects that stop the 生産／産物 of a 決定的な protein that 妨げるs muscle wastage.

    The 会議's Prof Terence Partridge said the 'antisense therapy' was in its 早期に days but had 抱擁する 可能性のある.
