Split hand foot malformation (SHFM) is a type of birth defect that consists of missing digits (fingers and/or toes), a deep cleft down the center of the hand or foot, and fusion of remaining digits.[1][2] The severity of this condition varies widely among affected individuals. SHFM is sometimes called ectrodactyly; however, this is a nonspecific term used to describe missing digits.[0] SHFM may occur by itself (isolated) or it may be part of a syndrome with abnormalities in other parts of the body. At least six different forms of isolated SHFM have been described. Each type is associated with a different underlying genetic cause. SHFM1 has been linked to chromosome 7, and SHFM2 is linked to the X chromosome. SHFM3 is caused by a duplication of chromosome 10 at position 10q24. Changes (mutations) in the TP63 gene cause SHFM4. SHFM5 is linked to chromosome 2, and SHFM6 is caused by mutations in the WNT10B gene. SHFM may be inherited in an autosomal dominant, autosomal recessive, or X-linked manner.

    • Many individuals want to know about healthcare professionals or researchers who have knowledge of their conditions. When a condition is rare, it can be difficult to find someone who has seen many cases. Although there is no list of experts in rare diseases, GARD's How to Find an Expert fact sheet provides several ways to identify healthcare professionals who have experience with a particular condition.

  • Testing

    • GeneTests lists laboratories offering clinical genetic testing for this condition. Clinical genetic tests are ordered to help diagnose a person or family and to aid in decisions regarding medical care or reproductive issues. Talk to your health care provider or a genetic professional to learn more about your testing options.

    • RDCRN 3rd Conference on Clinical Research for Rare Diseases, October 2, 2012
      Location: Hilton Washington DC/Rockville Hotel & Executive Meeting Center, Rockville, MD
      Description: Clinical research in rare diseases presents a number of challenges and unique issues that are not usually considered in the training of clinical investigators through existing training programs. Goals of the conference include: direct instruction of trainees and new investigators in rare disease research methodology; development of a reusable curriculum/syllabus on rare disease research methodology; and stimulation of ideas regarding the unique issues facing investigators engaged in the study of rare diseases.
    • VI International Conference on Rare Diseases and Orphan Drugs (ICORD 2010): Global Approach to Accessibility in Rare Diseases, Orphan Drugs and Neglected Diseases , March 18, 2010 - March 20, 2010
      Location: Palais Rouge Convention Center, Palermo, Buenos Aires
      Description: For the first time, the VI International Conference on Rare Diseases and Orphan Drugs (ICORD 2010) was convened in the southern hemisphere in agreement with its aim of globalization of rare diseases research and orphan products development activities.
 
Clinical Trials & Research (Found 6 resources)

    • The Centers for Mendelian Genomics program is working to discover the causes of rare genetic disorders. For more information about applying to the research study, please visit their website.
    • GeneTests lists laboratories offering research genetic testing for this condition. Research genetic tests may be used to find disease-causing genes, learn how genes work, or aid in the understanding of a genetic disorder. In many cases test results are not shared with the patient or physician. Talk to your health care provider or a genetic professional to learn more about research testing for this condition.
    • The University of California, San Francisco (UCSF) is conducting studies on isolated/non-syndromic limb malformations (syndactyly, polydactyly, split hand and foot, reduction anomalies, brachydactyly, clinodactyly, arachnodactyly, camptodactyly, etc.). They are collecting DNA samples of patients, both familial and sporadic, with isolated limb malformations. 

      DNA will be screened in order to discover novel mutations that lead to isolated limb malformations.  If clinically significant variants are discovered, the researchers will notify the referring clinician.  The research lab is not CLIA-certified, so test results must be confirmed in a CLIA-certified lab.

      Please contact the principal investigator, Dr. Nadav Ahituv, for further details.
