Most of the malignant cells displayed weak to moderate nuclear and occasional cytoplasmic positivity. A few cases of testicular cancers exhibited strong nuclear immunoreactivity. Most cases of renal, prostate, endometrial and liver cancers were negative.
Weak to moderate nuclear and cytoplasmic positivity was observed in most malignancies. A few cases of embyronal carcinomas of testis were strongly stained.
The majority of malignancies showed moderate to strong nuclear and cytoplasmic immunoreactivity. Most cases of malignant gliomas, lung, renal, liver, endometrial and prostate cancers were weakly stained or negative.

Description
MutS homolog 6 (HGNC Symbol)
Entrez gene summary
This gene encodes a member of the DNA mismatch repair MutS family. In E. coli, the MutS protein helps in the recognition of mismatched nucleotides prior to their repair. A highly conserved region of approximately 150 aa, called the Walker-A adenine nucleotide binding motif, exists in MutS homologs. The encoded protein heterodimerizes with MSH2 to form a mismatch recognition complex that functions as a bidirectional molecular switch that exchanges ADP and ATP as DNA mismatches are bound and dissociated. Mutations in this gene may be associated with hereditary nonpolyposis colon cancer, colorectal cancer, and endometrial cancer. Transcripts variants encoding different isoforms have been described.
