The symbols preceding the record number in OMIM have significance, including whether or not the record represents a phenotype that can be caused by a mutation in two or more genes. |
| Step By Step Guide |
|
OMIM
- Enter alveolar cell carcinoma in the search box and enter on the Go button
- Record 211980 Lung Cancer, Alveolar Cell Carcinoma Included is retrieved
- Note that the record number is preceded by the number # sign
A number symbol (#) before an entry number means that the phenotype can be caused by mutation in any of 2 or more genes.
The #-labeled entries are considered useful for avoiding repetition of the same phenotypic information in several entries and necessary because it is often unknown which genetic type is referred to in a particular report
