Cytogenetics

Cytogenetics morphological

The t(6;22)(p21;q12) was accompanied with a marker chromosome.

Genes Involved and Proteins

Gene name

POU5F1 (POU class 5 homeobox 1)

Location

6p21.33

Protein description

360 amino acids in the longest isoform; contains a bipartte DNA-binding domain, composed of a POU- specific domain (amino acids 138-212), and a homeobox (aa 230-289). Transcription factor with a major role during embryogenesis. Binds specifically ATTTGCAT.

Gene name

EWSR1 (Ewing sarcoma breakpoint region 1)

Location

22q12.2

Protein description

From N-term to C-term: a transactivation domain (TAD) containing multiple degenerate hexapeptide repeats, 3 arginine/glycine rich domains (RGG regions), a RNA recognition motif, and a RanBP2 type Zinc finger. Role in transcriptional regulation for specific genes and in mRNA splicing.

Result of the chromosomal anomaly

Description

5 EWSR1 - 3 POU5F1. Fusion of exons 1-6 of EWSR1 to part of exon 1, and exons 2-5 of POU5F1.

Description

The N terminal transactivation domain of EWSR1 was fused to the DNA binding domains of POU5F1.
