Tex22-flox Mouse

Tex22 is one of the genes located within a 0.305 Mb region on chromosome 14q32.33 [1]. While its exact function, associated pathways, and overall biological importance are not elaborated in the provided references, studies on genes in this region can potentially shed light on its role.

In a case report, a child with a microdeletion of chromosome 14q32.33, which includes Tex22 along with five other genes, presented with mild facial dysmorphisms and intellectual disability similar to patients with larger deletions of the long arm of chromosome 14. This suggests that the genes in this deletion, including Tex22, may contribute to the 14q32 deletion syndrome [1]. Additionally, Tex22 was identified as one of the protein-coding genes in a CRC-related competing endogenous RNA (ceRNA) network, with significantly high expression in colorectal cancer (CRC) according to validations in independent datasets [2].

In conclusion, Tex22 may play a role in the 14q32 deletion syndrome as indicated by the chromosomal deletion case, and its high expression in CRC implies a possible involvement in colorectal cancer development. Further functional studies, potentially using gene knockout or conditional knockout mouse models, could help elucidate its precise biological functions and its significance in these disease conditions.
