PDGFRB-related disorders, including Penttinen syndrome, Kosaki syndrome, and infantile myofibromatosis, have been successfully treated using imatinib. Here, we report a child diagnosed in infancy who initiated imatinib monotherapy at 8 months of age and has continued treatment for 4 years. At the time of diagnosis, he was known to have structural anomalies of the posterior fossa, sparse hair, joint stiffness, myofibromatosis, thin and fragile skin, decreased subcutaneous fat, and prominent vasculature. Imatinib has been well tolerated without apparent side effects. Within weeks to months after initiating imatinib, he grew thick curly hair, and the texture of his skin and joint stiffness had marked improvement. Over the past 4 years, he has not developed acroosteolysis and continues to have normal hair growth. Surveillance MRA has not identified aneurysms or vessel ectasia. Height decreased from 90th to 75th percentile. He has mild developmental delays and is awaiting formal evaluation for autism spectrum disorder. Overall, early imatinib treatment has been successful in ameliorating and preventing the development of some features of Penttinen syndrome.</p>","PeriodicalId":7445,"journal":{"name":"American Journal of Medical Genetics Part C: Seminars in Medical Genetics","volume":" ","pages":""},"PeriodicalIF":4.4,"publicationDate":"2025-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144752081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Reflective writing in the form of journaling can provide psychosocial support and help individuals cope with this diagnosis. Adult patients and parents whose children were evaluated at the Massachusetts General Hospital Myhre Syndrome Clinic were invited to participate in a three-month journaling intervention. Participation in the study required the completion of a series of surveys prior to starting and upon completion of the study. Data from these surveys were analyzed to assess for change in mental well-being. Eleven individuals participated, six of whom completed the three-month journaling intervention and post-journaling surveys. Three participants indicated that journaling had an impact on their mental well-being, and of these, two planned to continue journaling. However, there was no statistically significant difference in mental well-being scores pre- and post-journaling intervention.

Although the spectrum of CHDs in TS is well-established, with left-sided lesions predominating, the influence of specific karyotypes on the prevalence and types of CHDs remains incompletely understood. The primary objective of this systematic review/meta-analysis was to quantitatively synthesize the existing evidence on the association between specific karyotypes in TS and the risk of various CHDs. A systematic literature search was conducted through December 2023 to identify studies reporting the prevalence of CHDs in relation to TS karyotype. The quality of the individual studies was assessed using the Joanna Briggs Institute critical appraisal tools for systematic reviews. The overall estimates were pooled using both fixed- and random-effects models. Sensitivity and subgroup analysis were performed. Twenty-five studies were included in the analysis. TS individuals with a 45,X karyotype showed a significantly higher likelihood of bicuspid aortic valve (BAV) (pooled OR, 3.14 [95% CI: 2.49-3.94]), aortic coarctation (CoA) (pooled OR, 4.16 [95% CI: 2.74-6.31]), and partial anomalous pulmonary venous return (PAPVR) (pooled OR, 4.86 [2.31-10.2]) compared with TS individuals with a non-45,X karyotype. In addition, TS individuals with a 45,X karyotype also showed a significantly higher likelihood of BAV (pooled OR, 2.72 [95% CI: 1.62-4.56]) when compared with TS individuals with 45,X/46,XX mosaicism. TS individuals with a 45,X karyotype showed a significantly higher risk of BAV (pooled OR, 2.13 [95% CI: 1.42-3.21]) and CoA (pooled OR, 4.52 [95% CI: 1.58-13.0]) when compared with TS individuals with an isochromosome Xq. A significantly higher likelihood of BAV was also found in 45,X compared to other karyotypes (e.g., 45,X/46,XY and TS karyotypes with ring X chromosome). Some heterogeneity was evident, but publication was low. This meta-analysis confirms a strong association between the 45,X karyotype and increased prevalence of BAV, CoA, and PAPVR in TS. While 45,X/46,XX mosaicism and karyotypes with an isochromosome Xq mitigate risk, the findings emphasize the need for large-scale studies to refine risk assessment and management strategies.</p>","PeriodicalId":7445,"journal":{"name":"American Journal of Medical Genetics Part C: Seminars in Medical Genetics","volume":" ","pages":"e32146"},"PeriodicalIF":2.8,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144482788","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The dual sensory impairment associated with this autosomal recessive disorder makes Usher syndrome an important target for gene therapy, with dozens of published preclinical studies targeting multiple Usher syndrome genes and using multiple gene therapy strategies. Nine genes have been conclusively linked to Usher syndrome; however, data on the prevalence and contribution of specific genetic variants is lacking. Such information is essential to choosing a favorable target gene or therapeutic approach during clinical trial design. Here, we used large genomic databases to systematically evaluate the genomics of Usher syndrome. We ascertained pathogenic Usher syndrome variants from three clinical databases and determined the occurrence of these pathogenic Usher syndrome variants within: (1) a publicly available dataset including worldwide populations (GnomAD), (2) a cohort of 3888 children without hearing loss, and (3) 637 children with hearing loss. Results show significant variability in the frequency of Usher syndrome variants by gene and genetic ancestry. 1% of control subjects carry a pathogenic USH variant. Pathogenic variants in USH2A are the most prevalent, at 1 in 150 individuals (0.0062). Calculated general population prevalence for all Usher syndrome subtypes is 1 in ~29,000, indicating that 30,405 individuals in the United States and 721,769 individuals worldwide are affected. We estimate that 324 babies in the United States and 12,090 worldwide are born with Usher syndrome each year.

Extracted data was arranged in a review matrix, and study quality was assessed using a methodological quality score (MQS). Twenty-seven studies were selected for review, including 21 retrospective studies, five case reports, and one prospective study. The mean MQS across studies was 9.7 points (low to moderate). Across the included studies, nine categories of factors were investigated in association with parental decisions, including five pregnancy-related categories (ultrasound-detected abnormalities, karyotype, gestational age at diagnosis, time period of diagnosis, and prenatal counseling) and four categories related to expectant parents (age, reproductive history, expectations/concerns about the child's prognosis, and socio-demographic characteristics). Among these, ultrasound-detected abnormalities, karyotype, and counseling emerged as key factors influencing parental decisions.
