Orphanet J Rare Dis 2024; 19:255. [PMID: 38971792 PMCID: PMC11227184 DOI: 10.1186/s13023-024-03273-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2023] [Accepted: 07/01/2024] [Indexed: 07/08/2024] Open
Abstract
BACKGROUND The 22q11.2 Deletion Syndrome (22q11.2 DS) presents unique healthcare challenges for affected individuals, families, and healthcare systems. Despite its rarity, 22q11.2 DS is the most common microdeletion syndrome in humans, emphasizing the need to understand and address the distinctive healthcare requirements of those affected. This paper examines the multifaceted issue of health service access and caregivers' quality of life in the context of 22q11.2 DS in Brazil, a condition with diverse signs and symptoms requiring multidisciplinary care. This study employs a comprehensive approach to evaluate health service accessibility and the quality of life of caregivers of individuals with 22q11.2 DS. It utilizes a structured Survey and the WHOQOL-bref questionnaire for data collection. RESULTS Individuals with 22q11.2 DS continue to receive incomplete clinical management after obtaining the diagnosis, even in the face of socioeconomic status that enabled an average age of diagnosis that precedes that found in sample groups that are more representative of the Brazilian population (mean of 3.2 years versus 10 years, respectively). In turn, caring for individuals with 22q11.2 DS who face difficulty accessing health services impacts the quality of life associated with the caregivers' environment of residence. CONCLUSIONS Results obtained help bridge the research gap in understanding how caring for individuals with multisystem clinical conditions such as 22q11.2 DS and difficulties in accessing health are intertwined with aspects of quality of life in Brazil. This research paves the way for more inclusive healthcare policies and interventions to enhance the quality of life for families affected by this syndrome.

Neuropsychological Profile of 25 Brazilian Patients with 22q11.2 Deletion Syndrome: Effects of Clinical and Socioeconomic Variables. Genes (Basel) 2024; 15:595. [PMID: 38790224 PMCID: PMC11121403 DOI: 10.3390/genes15050595] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 04/25/2024] [Accepted: 05/03/2024] [Indexed: 05/26/2024] Open
Abstract
The 22q11.2 deletion syndrome (22q11.2DS) is associated with a heterogeneous neurocognitive phenotype, which includes psychiatric disorders. However, few studies have investigated the influence of socioeconomic variables on intellectual variability. The aim of this study was to investigate the cognitive profile of 25 patients, aged 7 to 32 years, with a typical ≈3 Mb 22q11.2 deletion, considering intellectual, adaptive, and neuropsychological functioning. Univariate linear regression analysis explored the influence of socioeconomic variables on intellectual quotient (IQ) and global adaptive behavior. Associations with relevant clinical conditions such as seizures, recurrent infections, and heart diseases were also considered. Results showed IQ scores ranging from 42 to 104. Communication, executive functions, attention, and visuoconstructive skills were the most impaired in the sample. The study found effects of access to quality education, family socioeconomic status (SES), and caregiver education level on IQ. Conversely, age at diagnosis and language delay were associated with outcomes in adaptive behavior. This characterization may be useful for better understanding the influence of social-environmental factors on the development of patients with 22q11.2 deletion syndrome, as well as for intervention processes aimed at improving their quality of life.

Genome Sequencing in an Individual Presenting with 22q11.2 Deletion Syndrome and Juvenile Idiopathic Arthritis. Genes (Basel) 2024; 15:513. [PMID: 38674447 PMCID: PMC11049871 DOI: 10.3390/genes15040513] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/20/2024] [Revised: 04/16/2024] [Accepted: 04/16/2024] [Indexed: 04/28/2024] Open
Abstract
Juvenile idiopathic arthritis is a heterogeneous group of diseases characterized by arthritis with poorly known causes, including monogenic disorders and multifactorial etiology. 22q11.2 proximal deletion syndrome is a multisystemic disease with over 180 manifestations already described. In this report, the authors describe a patient presenting with a short stature, neurodevelopmental delay, and dysmorphisms, who had an episode of polyarticular arthritis at the age of three years and eight months, resulting in severe joint limitations, and was later diagnosed with 22q11.2 deletion syndrome. Investigation through Whole Genome Sequencing revealed that he had no pathogenic or likely-pathogenic variants in both alleles of the MIF gene or in genes associated with monogenic arthritis (LACC1, LPIN2, MAFB, NFIL3, NOD2, PRG4, PRF1, STX11, TNFAIP3, TRHR, UNC13DI). However, the patient presented 41 risk polymorphisms for juvenile idiopathic arthritis. Thus, in the present case, arthritis seems coincidental to 22q11.2 deletion syndrome, probably caused by a multifactorial etiology. The association of the MIF gene in individuals previously described with juvenile idiopathic arthritis and 22q11.2 deletion seems unlikely since it is located in the distal and less-frequently deleted region of 22q11.2 deletion syndrome.

Variants in KMT2A in Three Individuals with Previous Suspicion of 22q11.2 Deletion Syndrome. Genes (Basel) 2024; 15:211.

Abstract
The condition known as 22q11.2 deletion syndrome (MIM #188400) is a rare disease with a highly variable clinical presentation including more than 180 features; specific guidelines for screening individuals have been used to support clinical suspicion before confirmatory tests by Brazil's Craniofacial Project. Of the 2568 patients listed in the Brazilian Database on Craniofacial Anomalies, 43 individuals negative for the 22q11.2 deletion syndrome were further investigated through whole-exome sequencing. Three patients (6.7%) presented with heterozygous pathogenic variants in the KMT2A gene, including a novel variant (c.6158+1del) and two that had been previously reported (c.173dup and c.3241C>T); reverse phenotyping concluded that all three patients presented features of Wiedemann-Steiner syndrome, such as neurodevelopmental disorders and dysmorphic facial features (n = 3), hyperactivity and anxiety (n = 2), thick eyebrows and lower-limb hypertrichosis (n = 2), congenital heart disease (n = 1), short stature (n = 1), and velopharyngeal insufficiency (n = 2). Overlapping features between 22q11.2 deletion syndrome and Wiedemann-Steiner syndrome comprised neuropsychiatric disorders and dysmorphic characteristics involving the eyes and nose region; velopharyngeal insufficiency was seen in two patients and is an unreported finding in WDSTS. Therefore, we suggest that both conditions should be included in each other's differential diagnoses.

Abstract
DiGeorge syndrome is associated with microdeletion of chromosome 22q11. Hypoplasia of the thymus, hypoparathyroidism, facial malformations and cardiac defects as well as learning difficulties are typical features of the disease. On the other hand hypocalcemia related to hypoparathyroidism is not present in every patient and can develop later and be persistent or transient and is often masked by the other signs or symptoms. We described a 13-year-old boy diagnosed with DiGeorge syndrome, after a few years of nonspecific signs and symptoms, and a microarray examination performed because myopathy was suspected on the basis of elevated creatine kinase activity. Only after molecular confirmation of DiGeorge syndrome the patient was referred to a pediatric endocrinologist and proper therapy started. Looking back to his medical history, low calcium levels were at least 2 times reported in the medical records, the child had learning difficulties, speech disturbances, and submucosal cleft palate suspicion. In conclusion it is important to educate general practitioners and pediatricians to check the serum calcium levels in patients presenting with nonspecific, muscular signs and symptoms.

Abstract
Abstract
Background
DiGeorge syndrome (DGS), caused by a deletion del(22)(q11.2q11.2), is the most frequently observed microdeletion syndrome. There is a vast clinical heterogeneity in DGS, and several studies suggested also heterogeneity of clinical signs and phenotypic appearance to be related to ethnic differences. Here, clinical characteristics of 72 patients with molecular diagnosed deletion del(22)(q11.2q11.2) derived from different countries from Europe, America, Africa, and Asia are summarized and compared.
Results
Unless ethnic differences, the expected major clinical signs were present in all cases. Frequent clinical manifestations found in this study were congenital heart disease with 68% (49/72), followed by dysmorphic features found in 61% (44/72); neurodevelopmental disorders were present in 43% (31/72) and thymus hypoplasia/aplasia in 32% (23/72). However, clinical features of the patients appeared/were recognized at different times during their lives. Within the group, under 2 years predominated heart disease, dysmorphic features, and hypocalcemia and/or hypoparathyroidism. In the group older than 2 years, the following combination of clinical findings was most frequent: dysmorphic features, congenital heart disease, intellectual disability, and immunological disorders. In the eight cases detected prenatally, abnormal sonographic findings were the major clinical signs (cardiovascular malformations and renal malformations).
Conclusions
Despite the heterogeneous nature of the sample analyzed, a number of clinical findings could be highlighted to be useful for the clinical delineation of this DGS. Interestingly, diagnostic indicators may vary depending on the age at diagnosis. Finally, apparent differences in DGS patients from different regions seem to be rather due to applied test systems than to real differences in patients from different ethnicities.
