Ciftciler R, Balasar Ö, Keyik H, Ciftciler AE. Hereditary thrombocytopenia with familial novel mutation in MYH9 gene: A familial case report. Transfus Apher Sci 2023; 62:103710. [PMID: 37076359 DOI: 10.1016/j.transci.2023.103710] [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: 10/22/2022] [Revised: 11/06/2022] [Accepted: 04/05/2023] [Indexed: 04/21/2023]
Abstract
One of the rarest types of hereditary thrombocytopenia is the MYH9-related disorder. This spectrum of disorders is characterized by large platelets with or without leukocyte inclusion bodies, a decrease in the total number of platelets, and autosomal dominant inheritance. Proteinuric nephropathy that frequently progresses to end-stage renal failure, as well as the beginning of progressive high-frequency sensorineural hearing loss in young adults, is also associated with MYH9-related disorder. In this case report, we presented three family members who had thrombocytopenia and in whom a heterozygous novel 22 bp deletion (c.4274_4295del) was detected which is located in exon 31 of the MYH9 gene. There was no evidence of bleeding in the family members we presented and thrombocytopenia was detected incidentally. Additionally, renal failure, hearing loss, presenile cataracts, and clinical symptoms were not detected in these family members. This novel mutation detected in the MYH9 gene has not been reported in the literature before.

The surgical management of a patient with chronic renal failure and macrothrombocytopenia related to the MYH9 gene mutation: A case report. SPECIAL CARE IN DENTISTRY 2022; 42:651-656. [PMID: 35537118 DOI: 10.1111/scd.12727] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2021] [Revised: 04/22/2022] [Accepted: 04/25/2022] [Indexed: 11/30/2022]
Abstract
MYH9 disease is a rare genetic disorder in which there is a mutation in the gene for the non-muscle myosin heavy chain IIA. It initially causes macrothrombocytopenia followed by other clinical manifestations. When the patient reaches adulthood, he can develop chronic kidney failure. Thus, the risk of suffering a hemorrhage, difficulty in repairing and, infections increases in individuals with this disease. In addition, the use of drugs in these patients should be carefully evaluated. An adult patient sought dental care with a complaint associated with a tooth with advanced dental caries. He had severe thrombocytopenia (7000 platelets/mm3 ), hearing loss, and chronic kidney failure. The diagnosis of MYH9 disease was confirmed through genotyping. After clinical examination, extraction was planned. Local and systemic procedures were used to prevent hemorrhage, especially postoperatively. Although the patient had an infection at the surgical wound site and no episode of postoperative bleeding, the repair process occurred normally. The purpose of this article is to report the surgical management of a patient with MYH9 disease.

Abstract
May-Hegglin anomaly is the presentation of a qualitative platelet disorder characterised by large platelets, thrombocytopenia and granulocyte inclusions as a result of mutations in the MYH9 gene. Though often overlooked given its rarity, it should be considered in patients who present with epistaxis, bruising, menorrhagia and easy bleeding as it can be mistaken for other diagnoses resulting in unnecessary treatments and tests. Our case study reports one presentation of this anomaly and can help broaden awareness of the presentation of this type of patient.
