• When will the FISH results be available?

Results typically take 5 to 10 business days due to the complex nature of the laboratory analysis.

• Can this test diagnose all genetic diseases?

No, it is specific to structural changes in the 12p region and does not cover all chromosomes or point mutations.

About this service

A specialized genetic test using Fluorescence In Situ Hybridization (FISH) to detect copy-number variations in the subtelomeric region of chromosome 12p, aiding in the diagnosis of rare genetic syndromes.

Importance of 12p Region Testing

Identifying copy-number variations (deletions or duplications).
Assisting in the diagnosis of unexplained developmental delays.
Evaluating congenital anomalies linked to chromosome 12.

Indications for the Test

Family history of syndromes associated with chromosome 12.
Screening newborns with atypical dysmorphic features.
Part of a comprehensive genetic evaluation for infertility or recurrent miscarriage.

How FISH Technology Works

Using fluorescent probes that bind to specific DNA sequences.
Examining cells under a specialized microscope to detect light signals.
Determining signal counts to diagnose abnormalities in the subtelomeric region.

What is included?

✓Blood sample collection
✓FISH laboratory analysis
✓Detailed genetic report

Conditions and notices

Fasting is not required
Preferably bring any previous medical reports regarding the genetic condition

Frequently Asked Questions

Short answers to the FAQs published with this service.

• What is the 12p FISH analysis?

It is a precise genetic test using fluorescent dyes to detect any deletions or duplications in the genetic material at the end of chromosome 12.

• Does the test require fasting?

No, this test does not require fasting or any specific dietary preparations.

• How is the sample collected?

A simple venous blood sample is drawn from the arm, which can be done at the laboratory or via home service.

• Why is the subtelomeric region specifically tested?

These regions are gene-rich and prone to rearrangements or mutations that can cause developmental issues.
