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. Diagnosing and managing PD presents significant challenges due to its rarity and the wide range of clinical and genetic variability. The main conditions in this group include Seckel syndrome, Microcephalic Osteodysplastic Primordial Dwarfism (MOPD) types I\/III, MOPD type II, Meier\u2013Gorlin syndrome, and Silver\u2013Russell syndrome (SRS). The first four\u2014Seckel syndrome, MOPD types I\/III, MOPD type II, and Meier\u2013Gorlin syndrome\u2014are associated with microcephaly, and together they are known as microcephalic PD. Given how uncommon PD is, establishing its exact incidence is difficult. It is estimated that about 4 million infants die within the first month of life, with 99% of these deaths occurring in the neonatal period. Materials and Methods. Accurately diagnosing PD requires meticulous evaluation, as it can be easily confused with other genetic disorders that also cause dwarfism. In this article, we present the case of a 10-year-old patient diagnosed with MOPD II, the most common and well-documented form of microcephalic PD. Results. Genetic analysis revealed a pathogenic variant in the PCNT (pericentrin) gene ((c.1550dup, p.Gln518Alafs*7), alongside a deletion of exons 37\u201341. Conclusions. This case sheds light on the clinical and genetic complexities of primordial dwarfism, underscoring the importance of timely and accurate diagnosis for effective patient care.<\/jats:p>","DOI":"10.3390\/medicina60111906","type":"journal-article","created":{"date-parts":[[2024,11,21]],"date-time":"2024-11-21T04:46:11Z","timestamp":1732164371000},"page":"1906","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Clinical Challenges in Diagnosing Primordial Dwarfism: Insights from a MOPD II Case Study"],"prefix":"10.3390","volume":"60","author":[{"given":"Alexandru Daniel","family":"Jurca","sequence":"first","affiliation":[{"name":"Department of Preclinical Disciplines, Faculty of Medicine and Pharmacy, University of Oradea, 410081 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8442-6791","authenticated-orcid":false,"given":"Codru\u021ba Diana","family":"Petchesi","sequence":"additional","affiliation":[{"name":"Department of Preclinical Disciplines, Faculty of Medicine and Pharmacy, University of Oradea, 410081 Oradea, Romania"},{"name":"Regional Center of Medical Genetics Bihor, County Emergency Clinical Hospital Oradea (Part of ERN-ITHACA), 410469 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S\u00e2nziana","family":"Jurca","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Pharmacy, University of Oradea, 410081 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3901-615X","authenticated-orcid":false,"given":"Emilia","family":"Severin","sequence":"additional","affiliation":[{"name":"Department of Genetics, \u201dCarol Davila\u201dUniversity of Medicine and Pharmacy\u2013Bucharest, Dionisie Lupu Street, Number 37, District 2, 020021 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Aurora Alexandra","family":"Jurca","sequence":"additional","affiliation":[{"name":"Faculty of Medicine and Pharmacy, University of Oradea, 410081 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claudia Maria","family":"Jurca","sequence":"additional","affiliation":[{"name":"Department of Preclinical Disciplines, Faculty of Medicine and Pharmacy, University of Oradea, 410081 Oradea, Romania"},{"name":"Regional Center of Medical Genetics Bihor, County Emergency Clinical Hospital Oradea (Part of ERN-ITHACA), 410469 Oradea, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,11,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1007\/s00438-015-1110-y","article-title":"Primordial Dwarfism: Overview of Clinical and Genetic Aspects","volume":"291","author":"Khetarpal","year":"2016","journal-title":"Mol.
