FOI 2023 10 - Full Genomic Sequencing


Information Requested:

In 2018, then Health and Social Care Secretary, Matt Hancock, announced the 'ambition to map 5 million genomes' as announced in this link:  

In this ambition, it was stated that:
'From 2019, all seriously ill children will be offered whole genome sequencing as part of their care.' 
'Adults with certain rare diseases or hard-to-treat cancers will also be offered the same option from 2019.' 

There are four questions I have based on these statements. 
1.    What is the total number of patients in Wales which been successfully mapped?
2.    What is the total number of adults mapped in Wales?
3.    What is the total number of patients in Wales mapped as a result of glioblastoma multiforme (GBM) diagnosis?
4.    What is the total number of patients in Wales mapped as a result of a diagnosed or suspected brain tumour?


Information provided for the answer:
