Test Description

The Comprehensive Short Stature Syndrome Panel looks at a broad set of genes linked to growth-related conditions. It is designed to help identify genetic causes of short stature, especially when the reason for slowed growth is unclear. This panel can support early diagnosis, guide personalized care, and provide helpful information for families and healthcare providers managing growth and developmental concerns.

  • Associated Conditions
    • Achondrogenesis type 1B
    • Achondrogenesis type 2
    • Achondrogenesis, type IA
    • Achondroplasia
    • Acrocallosal syndrome
    • Acrodysostosis
    • Acrodysostosis 2, with or without hormone resistance
  • Methodology

    Targeted Exome/ Slice Exome (Next Generation Sequencing including Copy Number Variation)

  • Limitations

    All sequencing technologies have limitations. A negative result from this analysis does not rule out a possible genetic diagnosis as some variants may not be detected by this test. This test is not designed to detect low level mosaicism, structural rearrangements, indels >40bp, deep intronic variants of unknown clinical significance, or large cytogenetic CNVs. Certain inherent qualities of the human genome, for example repetitive regions/homopolymers, GC rich, pseudogenes, and rare polymorphisms, pose significant technical challenges such as sequence misalignment that may potentially impact the accuracy of the results. False negative results may also occur in the setting of allogeneic bone marrow, stem cell transplantation, active or chronic hematologic conditions, recent blood transfusions, suboptimal DNA quality or PCR trace contamination. Other potential sources of error include sample mix-ups and clerical issues.
