Answer :
The unknown gene in the mouse probably encodes a protein similar to the paired box 2 (pax2) protein.
The function of the Pax2 gene
The PAX2 gene gives instructions for making a protein that is important in the development of the eyes, ears, brain and spinal cord (the central nervous system), kidneys, urinary tract, and genital tract during embryonic development.
Who is PAX3 gene-carrier?
Individuals with craniofacial-deafness-hand syndrome, a disorder marked by unusual facial features, substantial hearing loss, and abnormalities of the hand muscles that can limit movement, have at least one PAX3 gene variant (also known as a mutation).
