HDHD5-AS1: HDHD5 antisense RNA 1
CECR4 is adjacent to the human CES (Cat Eye Syndrome) critical region (CESCR), and at least 99 bp of overlap exists between CECR4 and the proximally adjacent gene, CECR5, which is transcribed in the opposite direction .
The sequences of exon 1 of HDHD5-AS1 is conserved in human and mouse .
CECR4 is adjacent to the human Cat Eye Syndrome critical region, and it may be involved in Cat Eye Syndrome .
Cat Eye Syndrome

|CECR3||cDNA||2.4 and 3.7||2.4 kb—predominantly in lung; 3.7 kg—weakly in all tissues|
