Moderate to strong cytoplasmic positivity was observed in hepatocellular carcinomas as well as a few cases of ovarian, gastric and pancreatic cancers. Cancer tissues in general were negative.
Most cancer tissues showed weak to moderate cytoplasmic staining with additional membranous positivity in some cases. A majority of carcinoids, gliomas, lymphomas, skin, urothelial and renal cancers were negative.
GENE INFORMATION
Gene name
OFD1 (HGNC Symbol)
Synonyms
71-7A, CXorf5, JBTS10, RP23
Description
Oral-facial-digital syndrome 1 (HGNC Symbol)
Entrez gene summary
This gene is located on the X chromosome and encodes a centrosomal protein. A knockout mouse model has been used to study the effect of mutations in this gene. The mouse gene is also located on the X chromosome, however, unlike the human gene it is not subject to X inactivation. Mutations in this gene are associated with oral-facial-digital syndrome type I and Simpson-Golabi-Behmel syndrome type 2. Many pseudogenes have been identified; a single pseudogene is found on chromosome 5 while as many as fifteen have been found on the Y chromosome. Alternatively spliced transcripts have been described for this gene but the biological validity of these transcripts has not been determined. [provided by RefSeq, Jul 2008]
