Same MESH ID for two different sub-type

Question

[1769mkc]

Can two MESH ID associated with two different sub type overlap or have same MESH ID .

For example

Acute M2 Myeloid Leukemia           C1879321    M2  D015470



Acute Undifferentiated Leukemia         C0280141    M0  D015456,D015470

This `

D015470

` is same for both the subtype.

The answer is yes. In this case, the MeSH term is a more general term for the two more specific concepts. In general, mappings between ontologies are not always perfect 1:1 mappings.
