Epidemiological characteristics of patients with Hutchinson-Gilford progeria syndrome and progeroid laminopathies in China. Pediatr Res 2024; 95:1356-1362. [PMID: 38191824 DOI: 10.1038/s41390-023-02981-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 11/21/2023] [Accepted: 12/06/2023] [Indexed: 01/10/2024]
Abstract
BACKGROUND Hutchinson-Gilford progeria syndrome (HGPS) and progeroid laminopathies (PL) are extremely rare genetic diseases with extremely poor prognoses. This study aims to investigate the epidemiological and genotypic characteristics of patients with HGPS/PL in China. METHODS Using a cross-sectional study design, general characteristics and genotypic data of 46 patients with HGPS/PL from 17 provinces in China were analyzed. RESULTS Among the 46 patients with HGPS/PL, 20 patients are HGPS, and the rest are PL; the identified total prevalence of HGPS/PL is 1/23 million. Among 42 patients with gene reports, 3 carried compound heterozygous mutations in the ZMPSTE24 while the other 39 carried LMNA mutations. Among PL, LMNA c.1579 C > T homozygous mutation was the most common. The onset of classic genotype HGPS is skin sclerosis in the first month after birth. The primary clinical manifestations of PL patients include skin abnormalities, growth retardation, and joint stiffness. The median age of onset for PL was 12 (6,12) months. CONCLUSIONS In China, the identified total prevalence of HGPS/PL is 1/23 million. 92.8% of the genetic mutations of HGPS/PL were located in LMNA, and the rest in ZMPSTE24. Most patients of HGPS/PL have skin abnormalities as the earliest manifestation. Compared to PL, the classic genotype HGPS starts earlier. IMPACT STATEMENT Hutchinson-Gilford progeria syndrome (HGPS) and progeroid laminopathies (PL) are extremely rare genetic diseases with extremely poor prognoses. To date, there is a paucity of epidemiological data related to HGPS/PL in China. This study first examined the genotypic, phenotypic, and prevalence characteristics of 40-50% of the cases of HGPS/PL in mainland China through a collaborative international registry effort. In China, the identified total prevalence of HGPS/PL is 1/23 million. 92.8% of the genetic mutations of HGPS/PL are located in LMNA. LMNA c.1579 C > T homozygous mutations are the most common form of gene mutations among the Chinese PL population.

Identification of Target Genes and Transcription Factors in Mice with LMNA-Related Dilated Cardiomyopathy by Integrated Bioinformatic Analyses. Med Sci Monit 2020; 26:e924576. [PMID: 32581210 PMCID: PMC7313426 DOI: 10.12659/msm.924576] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Accepted: 06/23/2020] [Indexed: 06/11/2023] Open
Abstract
BACKGROUND Dilated cardiomyopathy (DCM), which is characterized by enlarged ventricular dimensions and systolic dysfunction, is the most common type of cardiomyopathy. Mutations in the LMNA gene are reported in approximately 10% of familial DCM cases. However, the mechanism of LMNA mutations in human DCM remains unclear. MATERIAL AND METHODS We used the GSE36502 and GSE123916 datasets to obtain gene expression profiles from LMNA-related DCM mice and to identify differentially expressed genes (DEGs). Crucial function and pathway enrichment analyses of DEGs were performed. Protein-protein interaction (PPI) network analysis was carried out to identify the top 10 hub genes, which were validated using reverse transcription-polymerase chain reaction (RT-PCR) to find target genes. Weighted gene co-expression network analysis (WGCNA) was used to explore the module relevant to external traits of LMNA-related DCM mice. Transcription factors (TFs) for the selected genes were analyzed using NetworkAnalyst. RESULTS A total of 156 common DEGs (co-DEGs) were identified, including 80 up-regulated and 76 down-regulated genes. The enriched biological functions and pathways were oxidative stress, regulation of apoptosis, regulation of fibrosis, and MAPK pathways. Five target genes (Timp1, Hmox1, Spp1, Atf3, and Adipoq) were verified after RT-PCR. Most co-DEGs were discovered to be related to the development of external traits. Three TFs (ELF1, ETS1, and NRF1) showed close interactions with the hub genes. CONCLUSIONS Our study used integrated bioinformatic analyses and revealed some important genes in mice with LMNA-related DCM, which could provide novel insights into the mechanism underlying human LMNA-related DCM.

Luo DQ, Wang XZ, Meng Y, He DY, Chen YM, Ke ZY, Yan M, Huang Y, Chen DF. Mandibuloacral dysplasia type A-associated progeria caused by homozygous LMNA mutation in a family from Southern China. BMC Pediatr 2014; 14:256. [PMID: 25286833 PMCID: PMC4287574 DOI: 10.1186/1471-2431-14-256] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/19/2014] [Accepted: 10/01/2014] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Mandibuloacral dysplasia type A (MADA) is a rare autosomal recessive disorder, characterized by growth retardation, skeletal abnormality with progressive osteolysis of the distal phalanges and clavicles, craniofacial anomalies with mandibular hypoplasia, lipodystrophy and mottled cutaneous pigmentation. Some patients may show progeroid features. MADA with partial lipodystrophy, more marked acral, can be caused by homozygous or compound heterozygous mutation in the gene encoding lamin A and lamin C (LMNA). MADA and Hutchinson-Gilford progeria syndrome are caused by the same gene and may represent a single disorder with varying degrees of severity. MAD patients characterized by generalized lipodystrophy (type B) affecting the face as well as extremities and severe progressive glomerulopathy present heterozygous compound mutations in the ZMPSTE24 gene. CASES PRESENTATIONS We described a rare pedigree from Southern China, among them all three children presented with phenotypes of MADA associated progeria. The two elder sisters had developed severe mandibular hypoplasia associated progeria since the age of 1 year. The eldest sister showed a progressive osteolysis. The youngest son of 10 months showed severer lesions than those of his sisters at the same age, and presented possible muscle damage, and his symptoms progressed gradually. Three genes mutations including LMNA, ZMPSTE24 and BANF1 were tested in the family. LMNA gene sequencing revealed a homozygous missense mutation, c.1579C > T, p.R527C for all three siblings, and heterozygous mutations for their parents, whereas no mutations of ZMPSTE24 and BANF1 genes was detected among them. CONCLUSIONS The same homozygous mutation of c.1579C > T of LMNA gene led to MADA associated progeria for the present family. The course of osteolysis for MADA is progressive.
