Background:
De novo likely gene-disrupting variants of POGZ cause autism spectrum disorder (ASD) and intellectual disability. However, de novo missense variants of this gene were not well explored in neuropsychiatric disorders.
Methods:
The single-molecule molecular inversion probes-based targeted sequencing method was performed on the proband. Variant was validated using Sanger sequencing in both proband and parents. Immunoblot analysis was performed to examine the expression of POGZ in patient-derived peripheral blood lymphocytes. Published POGZ de novo missense variants in neuropsychiatric disorders were reviewed.
Results:
We detected a novel de novo missense variant in POGZ (c.1534C>A, p.H512N, NM_015100.4) in an individual with ASD. Immunoblot analysis revealed a dramatic reduction in POGZ protein in patient-derived peripheral blood lymphocytes suggesting a loss-of-function mechanism of this de novo missense variant. In addition, we collected and annotated additional eight POGZ de novo missense variants identified in neuropsychiatric disorders from literatures.
Conclusion:
Our findings will be beneficial to the functional analysis of POGZ in ASD pathogenesis, and for genetic counseling and clinical diagnosis of patients with POGZ de novo missense variants.

01:27Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

01:27Disorders of Leukocytes
Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
01:29Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
