Duchess Kate’s Sister, Pippa, Supports British HCM Charity

Published on by hcmbeat1 Comment

Pippa Middleton, who came to the public’s attention during the wedding of her sister Katherine to Prince William, has recently dedicated her efforts toward raising money for HCM genetic testing and research.  Middleton’s efforts are in honor of her late friend Miles Frost, who was lost to sudden cardiac arrest due to HCM in 2015. Frost’s father, British journalist and media personality David Frost, died from HCM just two years earlier in 2013, but this information was never communicated to the family.

The Miles Frost Fund, a partnership with the British Heart Foundation , helps families who have lost a member to a sudden death obtain genetic testing in order to learn if other family members are similarly affected. The Frost Fund also funds research by U.K.researchers working towards finding a cure for HCM.

Lack of Diversity in Gene Samples May Cause False HCM Diagnosis

A recent study published in The New England Journal of Medicine concluded that individuals of African descent found to carry genes previously identified with HCM did not, in fact, have the disease.  Thus, the article highlighted the importance of including diverse populations when sequencing genomes for genetic diseases so as to avoid false diagnoses.

The New York Times also picked up this story, focusing its article on the negative repercussions that can result from a false positive genetic test for HCM.

In connection with the findings, National Public Radio interviewed three people, including Dr. Isaac Kohane, one of the researchers who published the findings of the lack of diversity in the HCM genetic panel, as well as New York City HCM patient Tarika Mingo.  Finally, NPR spoke to veteran HCM expert Dr. Barry Maron, who noted a potential concern that athletes may have been erroneously disqualified from sports participation solely on the basis of false positive genetic testing results.

A recent article in Science Daily discussed findings of geneticists in the Netherlands which revealed the existence of  a mutation in the gene alpha-kinase 3 (ALPK3) which, if inherited from both parents, may cause severe cardiomyopathy in children.

Cardiomyopathy U.K. recently featured this story on their website.
