Functional Data Strengthen Clinical Validation of PhenoScore Phenotype-Guided AI for ANKRD11 Missense Variants.

Clinical genetics2026 Mar 05

KBG syndrome (KBGS, OMIM #148050) is a rare genetic disorder caused by heterozygous truncating or missense variants in the ANKRD11 gene or a deletion of 16q24.3 involving ANKRD11. While truncating variants clearly disrupt protein function, the interpretation of missense variants is more challenging, as many remain variants of uncertain significance (VUS). To address this, we evaluated PhenoScore, an open-source AI-based phenomics framework integrating facial recognition and medical data analysis, for predicting the pathogenicity of ANKRD11 missense variants and providing supporting evidence for variant interpretation within the ACMG framework, specifically the PP4 criterion. PhenoScore was trained on 79 individuals with truncating variants in ANKRD11 and age-, sex-, and ethnicity-matched controls with other neurodevelopmental disorders, and its performance was compared to AlphaMissense, REVEL, and the evaluation of a clinical geneticist. Six individuals with functionally confirmed pathogenic missense variants were used for testing. PhenoScore achieved high predictive accuracy with an area under the curve (AUC) of 0.95 and a Brier score of 0.089, and pathogenic missense variants in the test set received a mean prediction score of 0.94. PhenoScore significantly outperformed REVEL (p < 0.01), especially in cases supported by functional and clinical evidence, while no significant difference was observed compared to AlphaMissense (p = 0.63); importantly, the two tools showed complementary strengths. These findings suggest that PhenoScore represents a promising tool for clinical variant interpretation, as it quantifies phenotypic concordance with KBGS and provides objective evidence that can strengthen the PP4 criterion within the ACMG framework. Combined with molecular prediction tools like AlphaMissense, PhenoScore may help reduce uncertainty surrounding VUS in ANKRD11 by complementing these scores.

Clinical features and management of 16q24.3 microdeletion KBG syndrome: literature review.

Frontiers in pediatrics2026

KBG syndrome (KBGS) is an autosomal dominant disorder presenting with diverse clinical features. Although multiple cases of the microdeletion subtype have been reported, discussions regarding its phenotypic characteristics remain relatively limited. This study aims to summarize the clinical features and management strategies for pediatric KBGS patients caused by 16q24.3 microdeletions, thereby enhancing awareness of this rare disease. We conducted a retrospective analysis of the clinical manifestations, genetic characteristics, and clinical management of four pediatric patients with microdeletion-type KBGS at our institution, and systematically reviewed relevant literature to compile clinical data on affected patients. All four patients exhibited typical facial features (such as cupid's bow lip, protruding ears, and thick eyebrows), skeletal abnormalities, and ocular anomalies. Whole-exome sequencing revealed a 16q24.3 microdeletion encompassing the ANKRD11 gene. A literature review identified 68 cases (including the present cases) of KBG syndrome caused by 16q24.3 microdeletions, with a male-to-female ratio of 38:21 (9 cases of unknown sex), including 6 Chinese patients. Non-Chinese patients typically exhibit distinctive facial features including a prominent nasal root (14/28, 50%) and prominent forehead (15/33, 45.45%), whereas Chinese patients display characteristic facial features such as a cupid's bow lip, protruding ears, and thick eyebrows. Among the East Asian population (represented by Chinese individuals), the incidence of prominent eyebrows, cupid's bow lip, and delayed bone age was higher than in other populations. Patients with microdeletions involving only ANKRD11 exhibited a higher prevalence of the characteristic triangular facial appearance and intellectual disability. In this study, the two children received recombinant human growth hormone therapy, achieving catch-up growth with height increases of 1.66 standard deviations and 0.68 standard deviations, respectively. The clinical phenotype of patients with microdeletion-type KBGS mainly includes characteristic facial features, macrodontia, skeletal deformities, neurological abnormalities, and eye deformities. Cupid's bow lip, protruding ears, and thick eyebrows may be characteristic facial features of Chinese children with KBGS. Genetic testing is required for definitive diagnosis. Treatment primarily relies on multidisciplinary teams providing symptomatic supportive care, with the aim of achieving early diagnosis and treatment to improve patient outcomes.

Novel ANKRD11 Mutation in KBG Syndrome: A diagnostic triad of hearing loss, radiological macrodontia and artificial intelligence-assisted facial phenotyping.

Sultan Qaboos University medical journal2026

KBG syndrome is a rare autosomal dominant disorder characterised by developmental delay, characteristic facial features, macrodontia and skeletal anomalies, caused by mutations in the ANKRD11 gene. We report a 5.5-year-old Moroccan boy who presented in 2022 to a tertiary military teaching hospital in Rabat, Morocco, with psychomotor delay, autistic traits, epilepsy, bilateral hearing loss with chronic otomastoiditis and radiologically-detected macrodontia before clinical eruption, in whom artificial intelligence-assisted facial phenotyping suggested the diagnosis, subsequently confirmed by identification of a novel nonsense mutation (c.1977C>G; p.Tyr659Ter). Multidisciplinary management including antiepileptic therapy, speech therapy and audiological follow-up resulted in satisfactory seizure control and developmental progress.

Molecular Profiling of Polish Pediatric Patients with Epilepsy: A Single-Center Diagnostic Experience Using Next-Generation Sequencing.

Genes2026 Jan 27

Introduction: Epilepsy syndromes show marked clinical and genetic heterogeneity, with numerous functionally diverse genes involved in their etiology. Next-generation sequencing (NGS) has facilitated the identification of many monogenic epilepsy syndromes and enables earlier, more accurate diagnosis in pediatric patients. Materials and Methods: This study analyzes the molecular profiles of 87 pediatric patients with various forms of epilepsy in whom pathogenic or likely pathogenic variants were identified. Next-generation sequencing (NGS) using multi-gene epilepsy panels or whole-exome sequencing (WES) was performed. Results: A total of 88 pathogenic or likely pathogenic variants were detected in 48 epilepsy-related genes; 30 variants occurred de novo. SCN1A and KCNQ2 were the most frequent contributors (12.6% and 9.2%, respectively). The highest percentage of positive diagnoses (48%) was observed in patients with developmental and epileptic encephalopathy (DEE), with variants identified in genes including ALG13, ATP1A2, CACNA1A, CDKL5, CHD2, GABRG2, ITPA, KCNQ2, PCDH19, SCN1A, SCN2A, SCN3A, SCN8A, SMC1A, SPTAN1, STXBP1, and UBA5. Pathogenic variants in ANKRD11 were found in four patients with KBG syndrome, while other genes appeared sporadically. Conclusions: Targeted massively parallel sequencing is an effective diagnostic tool for pediatric epilepsy. The presence of numerous single-case findings highlights the high genetic heterogeneity of epilepsy. This approach enabled more precise diagnoses that would not have been achieved through clinical evaluation alone, underscoring the importance of genetic testing for prognosis and treatment planning in pediatric patients with unexplained epilepsy.

Expanding the Evaluation of Skeletal Anomalies in Patients With KBG Syndrome: Recommendations for Clinical Practice.

American journal of medical genetics. Part A2026 Feb 12

KBG syndrome is a rare autosomal dominant neurodevelopmental disorder caused by ANKRD11 haploinsufficiency and is characterized by short stature, distinctive facial features, intellectual disability or developmental delay, congenital anomalies and skeletal anomalies. Although skeletal anomalies are reported in about 75% of cases, their nature and extent in relation to growth are largely unknown. Therefore, this study aims to asses the prevalence of skeletal anomalies in KBG syndrome and explore whether there is a relationship with short stature. This retrospective cohort study includes patients with a confirmed diagnosis of KBG syndrome, with available radiographic images at the Radboud University Medical Center. The radiographs were re-evaluated by a radiologist focusing on the presence of spinal, costal, vertebral, and hand anomalies using standardized radiological criteria. In our cohort of 38 persons with KBG syndrome, 92% show skeletal anomalies on radiographic imaging. The most frequent observations on the radiographs were spinal anomalies (74%) and costal anomalies (40%). Specifically, lordosis (36%) had the highest prevalence. Patients with short stature (n = 14) showed higher prevalences of kyphosis and delayed skeletal age. In conclusion, this study demonstrates a high prevalence and broad variety of skeletal anomalies in individuals with KBG syndrome.
