Cutaneous mosaicism service
Specialist mosaic clinics are run at Great Ormond Street Hospital (GOSH) every Tuesday by Dr Veronica Kinsler and her team.Patients will often be seen once in the mosaicism service, have phenotyping and genetic investigations, and then be followed up by the most appropriate team within GOSH or locally.

Genetic testing and analysis
Where the genes are already known for particular diagnoses we offer blood tests and skin biopsies with genetic testing done in the diagnostic laboratories in GOSH.
Research into mosaic disorders
Where the genes are not already known for particular diagnoses, or where there is no diagnosis, or if the known genes transpire to be normal, we offer patients further investigation on a research basis.
