ABOVE is the twenty-four (24) hour day of CHROMOSOMIC CLOCK and this time is thirteen (#13).
Here I present: “Retinoblastoma”, Victor McKusick, Mendelian Inheritance in Man’, 1966. Retinoblastoma is caused by a congenital mutation in the 13q14.2 (retinoblastoma protein).
INTRODUCTION.
- Patients with 13q-syndrome are at risk of retinoblastoma when the RB1 gene, located in the chromosomal band 13q14.2, is deleted. The cytogenetic location hyperlink is 13q14.2 and genomic coordinates are 13:48,303,751-48,481,890. The screenshot of the 178,140 bp (base pairs) of DNA length is shown BELOW of the RB1 gene.
