Introdução

O que você precisa saber de cara

💬
EM LINGUAGEM SIMPLES

A Síndrome Seckel é uma condição genética rara que se inicia antes do nascimento e é caracterizada por nanismo proporcional e **microcefalia** (cabeça com tamanho menor que o esperado). As famílias costumam notar desde cedo o crescimento corporal reduzido, características faciais peculiares e desafios no desenvolvimento intelectual. Não existem remédios específicos voltados para a cura da síndrome, de modo que os cuidados concentram-se no acompanhamento das necessidades de cada pessoa. No Brasil, a doença não possui um protocolo clínico oficial (PCDT), mas o SUS disponibiliza procedimentos de reabilitação e exames genéticos na rede de atenção às doenças raras.

[Research advance on the clinical phenotypes and molecular genetic mechanisms of Microcephalic primordial dwarfism].

Zhonghua yi xue yi chuan xue za zhi = Zhonghua yixue yichuanxue zazhi = Chinese journal of medical genetics2026 Jan 10

Primordial dwarfism (PD) refers to a group of monogenic genetic disorders characterized by intrauterine growth restriction (IUGR) and severe, persistent postnatal growth retardation. These diseases have been associated with variants of multiple genes whose products are mainly involved in critical cellular biological processes such as maintenance of genomic stability, DNA damage repair, mRNA splicing regulation, and centrosome function. Variants of such genes can directly impair cell proliferation and developmental potential. With the widespread application of molecular genetic technologies such as high-throughput sequencing, significant progress has been made in the research of PD. This article focuses on the major subtypes of PD, including Seckel syndrome, Microcephalic osteodysplastic primordial dwarfism (MOPD) types I/III, MOPD type II, and Meier-Gorlin syndrome. It has systematically summarized the advances in their clinical phenotypic characteristics, pathogenic genes, and molecular mechanisms, with an aim to deepen the understanding of the essence of growth disorders associated with PD.

DNA2 enables growth by restricting recombination-restarted replication.

Nature2025 Oct

Nuclease-helicase DNA2 is a multifunctional genome caretaker that is essential for cell proliferation in a range of organisms, from yeast to human1-4. Bi-allelic DNA2 mutations that reduce DNA2 concentrations cause a spectrum of primordial dwarfism disorders, including Seckel and Rothmund-Thomson-related syndromes5-7. By contrast, cancer cells frequently express high concentrations of DNA2 (refs. 8-11). The mechanism that precludes cell proliferation in the absence of DNA2 and the molecular aetiology of DNA2-linked diseases remain elusive. Here we used yeast and human cells to demonstrate that DNA2 suppresses homologous recombination-restarted replication and checkpoint activation at stalled DNA replication forks. Loss of this control mechanism upon degradation of DNA2 in human cells causes recombination-dependent DNA synthesis and build-up of RPA-bound single-stranded DNA in the G2 phase of the cell cycle. Consequently, DNA2 deprivation triggers the DNA damage checkpoint and invariably leads to ATR-p21-dependent cell-cycle exit before mitosis. These findings explain why DNA2 is essential for cell proliferation and reveal that replication fork processing to restrict recombination is indispensable for avoiding cellular senescence. Stochastic entry into senescence stifles the proliferative potential of cells following the expression of a Seckel syndrome patient-derived DNA2 hypomorph or partial degradation of DNA2, providing a conceptual framework to explain global growth failure in DNA2-linked primordial dwarfism disorders.

Case Report: Compound heterozygous CEP152 c.3346-5T>C variant and chr15 deletion causing recurrent MCPH-SCKS in a Chinese pregnant woman across two consecutive pregnancies.

Frontiers in genetics2025

Primary autosomal recessive microcephaly and Seckel syndrome spectrum (MCPH-SCKS) disorders are a group of autosomal recessive conditions characterized by severe growth retardation and neurodevelopmental impairment. CEP152 variants are established causes of both microcephaly and Seckel syndrome phenotypes, but the pathogenicity of different variant combinations and their clinical recurrence patterns require further verification with additional cases. Clinical and genetic analyses were performed for two consecutive pregnancies of a non-consanguineous Chinese couple. Fetal phenotypes were evaluated by ultrasound and fetal MRI sequentially; copy number variation sequencing (CNV-seq) was used to detect large genomic variants, whole-exome sequencing (WES) to screen for point variants, and minigene splicing assays to characterize the functional impact of key variants. Fetuses in both pregnancies were diagnosed with MCPH-SCKS and harbored identical compound heterozygous CEP152 variants: a paternally inherited splice-site variant c.3346-5T>C and a maternally inherited 129.6 kb chromosomal deletion localized to 15q21.1, encompassing the entire CEP152 gene. Minigene assays confirmed that the c.3346-5T>C variant caused aberrant splicing via intron retention and exon skipping, clarifying its pathogenicity. The second pregnancy in 2024 independently verified the pathogenicity of this variant combination and disease recurrence. This study represents the first report of identical compound heterozygous CEP152 variants causing MCPH-SCKS in two consecutive pregnancies. The independent occurrence in the second pregnancy not only confirms the pathogenicity of this variant combination but also provides clinical evidence for the 25% recurrence risk of autosomal recessive disorders. Furthermore, this report underscores the critical importance of comprehensive genetic testing, including CNV analysis, for the prenatal diagnosis of MCPH-SCKS, offering valuable guidance for genetic counseling and prenatal intervention in similar families.

ST-Elevation Myocardial Infarction (STEMI) in a Morphologically Pediatric Adult With Seckel Syndrome: A Report of a Rare Case.

Cureus2025 Sep

Seckel syndrome is a rare genetic disorder characterized by severe growth retardation, microcephaly, and distinctive craniofacial features. Although cardiovascular anomalies have been sporadically reported, ST-elevation myocardial infarction (STEMI) has not been documented in this population. To the best of our knowledge, we present the first case of anterior STEMI in a 30-year-old male with Seckel syndrome. The patient, weighing 11.5 kg, presented with acute chest and back pain and was diagnosed with anteroseptal STEMI. His complex medical history, including a coiled intracranial aneurysm, precluded thrombolysis, while his small body size and the absence of pediatric-compatible equipment rendered percutaneous coronary intervention (PCI) unfeasible. Despite maximal intensive care support, the patient developed multiorgan failure and died. This case highlights the expanding cardiovascular manifestations of Seckel syndrome and the difficulties in applying standard STEMI management protocols to morphologically pediatric adults. The lack of specialized interventional tools and infrastructure in many regions further complicates care. This underscores the urgent need for multidisciplinary care models and specialized pediatric interventional cardiology services for syndromic adults.

Expanding the Clinical Phenotype Associated with the NIN Gene; Report of a Patient with Short Stature, Microcephaly and Hearing Loss.

Archives of Iranian medicine2025 May 01

To date, there are very few reports regarding patients with bi-allelic variants in the NIN gene. There is one report of two sisters with severe short stature, microcephaly, and developmental delay with compound heterozygote missense variants in the NIN gene and one paper reporting a homozygote variant in the NIN gene with progressive, high-frequency sensorineural hearing loss in four siblings. The only other report is of four members of a consanguineous family with spondyloepimetaphyseal dysplasia with joint laxity-leptodactylic type (SEMDJL2) with a homozygous variant in the NIN gene. Given the scarcity of cases with NIN variants, the relationship between the phenotype and gene is provisional and our case broadens the phenotypic spectrum regarding the phenotype related to NIN gene variants. Here, we report a patient with a homozygous variant in exon 2 of the NIN gene defined as c.3407_3409del (p.Glu1136del). Clinical findings in our patient were characteristic of microcephalic primordial dwarfism (MPD) including microcephaly, prominent nose, intellectual disability and severe short stature. In addition, this patient had bilateral hearing loss, which was not reported in the patients with MPD and variant in the NIN gene before. We identified a novel p.Glu1136del variant in the NIN gene, predicted to disrupt critical centrosome-related pathways. WES was reanalyzed for other genes which are known for deafness and no variant was identified. A family history of deafness was not present in the pedigree. This is the first report of a patient with MPD and deafness associated with the NIN gene.
