Does dependant tourist Visa checked against ILR details

[a_lvss]

hello there,

My situation : I came to UK on work permit and now holding ILR

what i want to achieve : Get my parents here on a visit

my issue : My mom doesn't have an official date of birth.

my question : I reckon I have given a date of birth of my mom's which we all assumed in the family in my Tier 2 application, apparently , there seems to be a mistake made in passport on the Date of birth - means the two dates differ. now, when she is applying for tourist visa to UK , will that be referred against by Tier 2 application information for comparison if i'm her sponsor?

i know i might be sounding stupid; please help
