A novel frameshift mutation of SOX10 identified in Waardenburg syndrome type 2.

Human molecular genetics2025 Apr 06

Waardenburg syndrome type 2 (WS2) is an autosomal dominant disorder characterized by congenital sensorineural hearing loss, blue iris, and abnormal pigmentation of the hair and skin. WS2 is genetically heterogeneous, often resulting from pathogenic mutations in SOX10 gene. We identified a novel heterozygous frameshift mutation in SOX10 (NM_006941.4: c.22delT, p.S8Rfs*5) in a two-generation Chinese family with WS2 through whole exome sequencing. This mutation was present in both the proband, who exhibited typical features of hearing loss and pigmentation abnormalities, and his father, who showed only mild facial features. Quantitative real-time PCR revealed that the frameshift mutation leads to a reduced expression levels of SOX10 in the peripheral blood of mutation carriers. Our findings expand the spectrum of pathogenic mutations in SOX10 associated with WS2, providing valuable information for prenatal diagnosis and preimplantation screening, and underscore the role of genetic diagnosis in identifying atypical patients.

Clinical Characteristics and Identification of Pathogenic Variant in a Large Chinese Family With Waardenburg Syndrome.

Molecular genetics &amp; genomic medicine2025 Sep

Waardenburg syndrome is a genetic disorder characterized by sensorineural hearing loss and abnormal pigmentation. This study aims to explore the pathogenic variant in a large Waardenburg syndrome family and provide a theoretical basis for prenatal diagnosis of related family members. The clinical phenotype of the family members was analyzed. DNA was extracted from collected peripheral blood samples, and then exome sequencing and Sanger sequencing were performed. The pathogenicity of the genetic variant was evaluated by bioinformatics analysis. Amniocentesis was performed on the proband's mother (III13) to collect amniotic fluid samples for prenatal diagnosis. There were 13 patients in the family. Most of the patients presented with deafness and abnormal pigmentation of hair or eyes, which was consistent with the diagnosis of Waardenburg syndrome type 2. Exome sequencing revealed a heterozygous variant of the SOX10 gene (NM_006941.4: c.386T>C (p.Leu129Pro)) in the proband. Sanger sequencing showed that the variant co-segregated with the disorder in this family. This variant has not been previously reported in relevant databases. The site p.Leu129 was highly conserved among various species and was important for protein structure and function. In this study, we reported a family with autosomal dominant Waardenburg syndrome type 2 and identified a heterozygous variant of the SOX10 gene by exome sequencing. In addition, prenatal diagnosis and genetic counseling were provided to the family related individual.

Identification of the Mitf gene mutation causing congenital deafness and pigmentation disorders in porcupines using BSA-Seq.

Scientific reports2024 Dec 28

Worldwide, congenital deafness and pigmentation disorders impact millions with their diverse manifestations, and among these genetic conditions, mutations in the Microphthalmia-associated transcription factor (MITF: OMIM#156845) gene are notable for their profound effects on melanocyte development and auditory functions. This study reports a novel porcupine model exhibiting spontaneous deafness and pigmentation abnormalities reminiscent of human Waardenburg Syndrome Type 2 (WS2: OMIM#193510). Through phenotypic characterization, including coat color, skin, eye morphology, and auditory brainstem response (ABR) assessments, we identified hypopigmentation and complete deafness in mutant porcupines. To pinpoint the genetic basis, a breeding program was established, and Bulk Segregant Analysis (BSA) combined with RNA sequencing was conducted. Primers based on the identified candidate genes were designed for PCR amplification, followed by verification through Sanger sequencing. Through BSA analysis, we identified a total of 88 SNP and 336 InDel candidate sites. By annotating the Mitf gene, we obtained four unique transcript sequences. The SNP and InDel sites within the porcupine Mitf gene sequence, identified through BSA screening, were analyzed in conjunction with the gene's annotation results. This analysis revealed a specific mutation site, Mitf c.875_877delGAA p. (Arg217del), which was subsequently verified by Sanger sequencing. This naturally occurring Mitf mutation in porcupines provides a valuable model for studying the mechanisms underlying WS2 and exploring potential therapeutic strategies for deafness and pigmentation-related disorders.

Asymmetric preservation of choroidal pigmentation simulating choroidal nevus in two siblings with Waardenburg syndrome type 2A.

Ophthalmic genetics2024 Oct

In addition to sensorineural hearing loss, Waardenburg Syndrome (WS) may present with variable pigmentation of skin and choroid, which may simulate other life-threating conditions (e.g. melanoma). Two siblings ostensibly presented with unilateral choroidal pigmentary abnormalities concerning for choroidal tumour. Serial ophthalmic examination documented no lesion growth (base or height) whilst the apparent syndromic features (i.e. iris hypochromia, profound sensorineural hearing loss, SNHL), family history (autosomal dominant inheritance) and positive genetic testing (pathogenic MITF variant) led to a revised diagnosis of Waardenburg Syndrome type 2A. Sectoral preservation of choroidal pigmentation in WS is rarely associated with choroidal malignancy. Awareness of syndromic features (e.g. SNHL) and access to genetic testing may facilitate early accurate diagnosis (i.e. allay concern for malignancy), enable treatment of modifiable features (e.g. SNHL) and identify other affected relatives.

Waardenburg syndrome type 2 with a de novo variant of the SOX10 gene: a case report.

BMC medical genomics2024 Apr 24

Waardenburg syndrome type 2 (WS2) has been reported to be a rare hereditary disorder, which is distinguished by vivid blue eyes, varying degrees of hearing impairment, and abnormal pigment deposition in the skin and hair. Variants in the sex-determining region Y-box containing gene 10 (SOXl0) gene may cause congenital deafness and have been demonstrated to be important during the development of WS2. Complete clinical data of the proband and her family members (her parents and 2 sisters) was collected and physical examinations were performed in the hospital. The laboratory examination including hemoglobin, Coomb's test, urine protein, ENA, autoimmune hepatitis-related autoantibodies and ultrasonography were all conducted. We obtained the peripheral blood samples from all the participants and performed whole exome sequencing and sanger sequencing validation. The present study identified a family of 5 members, and only the proband exhibited typical WS2. Beyond the characteristics of WS2, the proband also manifested absence of puberty. The proband and her younger sister manifested systemic lupus erythematosus (SLE). Whole exome sequencing revealed a de novo variant in the SOX10 gene. The variant c.175 C > T was located in exon 2 of the SOX10 gene, which is anticipated to result in early termination of protein translation. The present study is the first to report a case of both WS2 and SLE, and the present findings may provide a new insight into WS2.
