Marfan Syndrome Associated With Intellectual Disability and Behavioral Anomalies: Further Evidence for the Effect of Compound Heterozygous Variants in FBN1 on Phenotypic Severity

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Marfan syndrome (MFS) is a rare connective tissue disorder characterized by involvement of the cardiovascular, ocular, and musculoskeletal systems. Pathogenic variants in FBN1 cause most of the MFS cases; however, intellectual disability (ID) is rarely observed. A non‐consanguineous Pakistani family with four affected individuals was recruited.

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

The Anatomical Record, EarlyView.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Prevalence of tooth agenesis and supernumerary teeth related to different Thai cleft lip and cleft palate populations

BMC Oral Health
Pattern of dental anomalies encountered in cleft patients shows subtle signs of genetic involvement. This study aimed to evaluate the prevalence and pattern of tooth agenesis and supernumerary teeth in Thai cleft population according to the cleft type ...

Algorithm for Treatment of Supernumerary Nasal Tooth

Journal of Craniofacial Surgery, 2021
Abstract The presence of a tooth in the nasal cavity is a rare condition. There is an even more rare association, which is the presence with the mineral's deposition and formation of rhinoliths. This report shows a case of rare nasal tooth associated with rhinolithiasis and describes its surgical treatment based on an algorithm.

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, EarlyView.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

FAM20B-catalyzed glycosaminoglycans control murine tooth number by restricting FGFR2b signaling

BMC Biology, 2020
Background The formation of supernumerary teeth is an excellent model for studying the molecular mechanisms that control stem/progenitor cell homeostasis needed to generate a renewable source of replacement cells and tissues.
