is a rare group of genetic conditions where individuals experience severe growth restriction, both in the womb and after birth. From as early as the fetal stage, those affected are significantly smaller than their peers. What makes PD distinct is its slow but steady growth pattern, resulting in proportionate dwarfism, where all parts of the body are equally shortened.

Unlabelled: Seckel syndrome, also commonly called Seckel dwarfism, is a rare congenital disorder and always associated with severe growth retardation . This retarded growth lingers on and causes serious developmental deformities ensuing to short stature, microcephaly, mental retardation, and a beak-like nose. This case report intends to present an interesting case of a 14-year-old female patient with various clinical manifestations, typical radiographic features, and characteristic dental manifestations correlated with the literature.

Ninein (Nin) is a microtubule (MT) anchor at the subdistal appendages of mother centrioles and the pericentriolar material (PCM) of centrosomes that also functions to organize MTs at noncentrosomal MT-organizing centers (ncMTOCs). In humans, the gene is mutated in Seckel syndrome, an inherited developmental disorder. Here, we dissect the protein domains involved in Nin's localization and interactions with dynein and ensconsin (ens/MAP7) and show that the association with ens cooperatively regulates MT assembly in fat body cells.

Sella turcica is an important anatomical structure that contains the pituitary gland. Changes observed on the sella turcica facilitate the identification of diseases such as Down syndrome, Seckel syndrome and tuberculum sellae meningioma in humans. Therefore, studies in this region are critical for a better understanding of sella turcica.

The human DNA repair factor CtIP helps to initiate the resection of double-stranded DNA breaks for repair by homologous recombination, in part through its ability to bind and bridge DNA molecules. However, CtIP is a natively disordered protein that bears no apparent similarity to other DNA-binding proteins and so the structural basis for these activities remains unclear. In this work, we have used bulk DNA binding, single molecule tracking, and DNA bridging assays to study wild-type and variant CtIP proteins to better define the DNA binding domains and the effects of mutations associated with inherited human disease.
