Haemoglobin (Hb) AE Bart's disease is a rare form of thalassemia that results from the co-inheritance of Hb E and alpha thalassemia, typically with Hb H disease. The clinical severity can vary depending on the underlying genetic mutations, particularly in the presence of Hb Constant Spring (Hb CS), which is a highly unstable form of alpha thalassemia. Understanding the genetic basis and haematological profiles of Hb AE Bart's disease is crucial for proper diagnosis and management.

Genotype-phenotype correlation and potential genetic risk in the compound heterozygosity for unstable hemoglobins (UHbs) and α-thalassemia were discussed. Capillary electrophoresis and gene sequencing helped to establish the diagnosis. Hematological analysis showed the following findings: MCV 80.

The MYST family histone acetyltransferase gene, KAT6B (MYST4, MORF, QKF) is mutated in two distinct human congenital disorders characterised by intellectual disability, facial dysmorphogenesis and skeletal abnormalities; Say-Barber-Biesecker-Young-Simpson variant of Ohdo syndrome and Genitopatellar syndrome. Despite its requirement in normal skeletal development, the cellular and transcriptional effects of KAT6B in skeletogenesis have not been thoroughly studied. Here, we show that germline deletion of the Kat6b gene in mice causes premature ossification in vivo, resulting in shortened craniofacial elements and increased bone density, as well as shortened tibias with an expanded pre-hypertrophic layer, as compared to wild type controls.

Split-hand/foot malformation syndrome (SHFM) is a congenital limb malformation that is both clinically and genetically heterogeneous. Variants in WNT10B are known to cause an autosomal recessive form of SHFM. Here, we report a patient born to unrelated parents who was found to be a compound heterozygote for missense variants in WNT10B: c.

Cases of microtia combined with pulmonary hypoplasia are occasionally in clinics, and its genetic etiology has so far proved inconclusive. Here, aiming to contribute to a better understanding of microtia-related comorbid respiratory anomalies, the authors provide a clinical and genetic description of a rare trio family of which the son suffers combined deformities of right microtia, left pulmonary hypoplasia, and dextrocardia using whole-genome sequence (WGS). A novel potential pathologic compound heterozygosity in the FREM1 gene was identified and validated by the trio and bioinformatics analysis.
