We are happy to accommodate requests for testing single genes in this panel or a subset of these genes. The price will remain the list price. If desired, free reflex testing to remaining genes on panel is available. Alternatively, a single gene or subset of genes can also be ordered via our Custom Panel tool.
An additional 25% charge will be applied to STAT orders. STAT orders are prioritized throughout the testing process.

18 days on average for standard orders or 13 days on average for STAT orders.
Please note: Once the testing process begins, an Estimated Report Date (ERD) range will be displayed in the portal. This is the most accurate prediction of when your report will be complete and may differ from the average TAT published on our website. About 85% of our tests will be reported within or before the ERD range. We will notify you of significant delays or holds which will impact the ERD. Learn more about turnaround times here.

Clinical Features and Genetics
Congenital syndactyly is defined as joined fingers or toes by soft tissue or by bone. It is one of the most common limb birth defects with an estimated incidence of 1 in 2,000 to 3,000 live births. This condition is caused by failed separation during embryonic development (Ahmed et al. 2017. PubMed ID: 29263957; Tonkin. 2009. PubMed ID: 19380059). It may manifest as an isolated (non-syndromic) case or as part of more than 300 syndromic conditions. Syndactyly can present unilateral/bilateral, finger/toe; complete or partial (Malik. 2012. PubMed ID: 22333904; Deng and Tan. 2015. PubMed ID: 26069458; Tonkin. 2009. PubMed ID: 19380059).
Molecular genetic testing is advantageous to establish an accurate diagnosis for individuals with a variety of syndactyly conditions. Co-features of many of these conditions may require medical attention.
This panel includes genes associated with a variety of genetic syndactyly disorders that have been identified through literature, OMIM, and HGMD searches. The patterns of inheritance of the condition can be autosomal dominant (AD), autosomal recessive (AR) or X-linked (XL) (Al-Qattan. 2019. PubMed ID: 31637260). Examples include Split-hand/foot malformation (also known as ectrodactyly), FGFR2-related conditions (Apert syndrome, LADD syndrome, and Saethre-Chotzen syndrome), HOXD13-related Syndactyly, Robinow syndrome, TP63-related conditions, Lenz-Majewski hyperostotic dwarfism, Temtamy preaxial brachydactyly syndrome, Squalene synthase deficiency, Filippi syndrome, Roberts syndrome, Metacarpal 4-5 fusion, Bartsocas-Pappas syndrome, and Cenani-Lenz syndactyly syndrome.

Clinical Sensitivity - Sequencing with CNV PGxome
In one study, pathogenic variants were found in 18% (36/199) of patients with a genetic etiology of congenital upper limb defects. Among them, 13/199 cases had a copy number variation at the chromosomal level, and 23/199 cases were found to have a pathogenic variant involving a single nucleotide substitution, or small deletion/insertion (Carli et al. 2013. PubMed ID: 24343878).
This test is able to detect both large copy number variation (large deletions and insertions) (CNV) as well as smaller sequence variants (SNVs) with high analytical sensitivity.
This test is performed using Next-Gen sequencing with additional Sanger sequencing as necessary.
This panel typically provides 99.2% coverage of all coding exons of the genes plus 10 bases of flanking noncoding DNA in all available transcripts along with other non-coding regions in which pathogenic variants have been identified at PreventionGenetics or reported elsewhere. We define coverage as ≥20X NGS reads or Sanger sequencing. PGnome panels typically provide slightly increased coverage over the PGxome equivalent. PGnome sequencing panels have the added benefit of additional analysis and reporting of deep intronic regions (where applicable).
Dependent on the sequencing backbone selected for this testing, discounted reflex testing to any other similar backbone-based test is available (i.e., PGxome panel to whole PGxome; PGnome panel to whole PGnome).
