The effects of the mutations were rationalized based on homology modeling of the Dmp53 DNA-binding domain, suggesting that the drastically different effects of a cancer mutation in the loop-sheet-helix motif (R282W in Hp53 and R268W in Dmp53) on stability and DNA binding affinity of the two proteins are related to conformational differences in the L1 loop adjacent to the mutation site.

Two family members without a TP53 germline mutation who developed peripheral schwannomas also carried the MSH4 germline mutation, and in addition, a germline mutation of the LATS1 gene (c.286C>T; p.R96W).
