Identification of Novel and Rare GNAS Mutations in Craniofacial Fibrous Dysplasia.

Background: Fibrous dysplasia (FD), caused by activating mutations of GNAS, is a skeletal disorder with considerable clinicopathological heterogeneity. Although prevalent mutations such as R201C and R201H dominate in FD, a limited number of rare mutations, including R201S, R201G, and Q227L, have been documented. The scarcity of information concerning these uncommon mutations motivates our investigation, seeking to enhance comprehension of this less-explored subgroup within FD.

Deciphering odontogenic myxoma: the role of copy number variations as diagnostic signatures.

In light of the lack of reliable molecular markers for odontogenic myxoma (OM), the detection of copy number variation (CNV) may present a more objective method for assessing ambiguous cases.

This allowed us to reveal the CNV profiles of OM and compare them with dental papilla (DP), dental follicle (DF), and odontogenic fibroma (OF) tissues.
