Genética e causas

O que está alterado no DNA e como passa nas famílias

🧬

Condição cromossômica — cromossomo X

Causada pela perda de material do cromossomo X. O fenótipo resulta da alteração na dose de múltiplos genes simultaneamente — não há gene causal único. Diagnóstico por cariótipo, CMA ou FISH.

Aneuploidias de X têm fenótipo mais leve devido à inativação de X (lyonização). SHOX (Xp22.33 pseudoautossômica) explica baixa estatura em Turner.

Variant phenotypic expression of mosaic Turner syndrome with type II MRKH (MURCS association).

BMJ case reports2026 Jan 07

We present a rare case of an unmarried woman in her mid-twenties with primary amenorrhoea who was found to have the unusual coexistence of mosaic Turner syndrome (45, XO/46, XX) and Mayer-Rokitansky-Küster-Hauser syndrome with MURCS association (Müllerian agenesis, Renal anomalies, Cervicothoracic Somite dysplasia). The patient exhibited normal secondary sexual characteristics and was phenotypically female. The patient underwent successful laparoscopic Davydov vaginoplasty in anticipation of marriage. This case highlights the diagnostic complexity and management challenges associated with dual congenital anomalies that affect both gonadal and Müllerian development.

Identification of autosomal and sex chromosome aneuploidies using next generation sequencing.

Bioinformatics (Oxford, England)2026 Mar 16

Chromosomal abnormalities, referred to as aneuploidies, occur in approximately 0.3% of live births. While the majority of aneuploidies in humans are incompatible with life, well-characterized exceptions include Down syndrome (47,+21), Patau syndrome (47,+13), Edwards syndrome (47,+18), Turner syndrome (45, X0), Klinefelter syndrome (47, XXY), and triple X syndrome (47, XXX). These chromosomal alterations disrupt gene expression and cellular function, leading to genetic and developmental disorders. With the increasing adoption of next-generation sequencing (NGS) in clinical diagnostics, this study aims to explore the potential use of NGS for aneuploidies detection. Using data derived from clinical exomes (CES) and whole exomes (WES) sequencing we have been able to detect autosomal as well as sex chromosome aneuploidies with high specificity. Moreover, we have also been able to identify mosaic aneuploidies proving the high sensibility of this methodological approach. Thus, we present NGS as a cost-effective first line approach to detect chromosomal aneuploidies in routine diagnostic practice. Scripts are available at https://github.com/B-R-I-D-G-E/AneuploidiesStudies. Supplementary data are available at Bioinformatics online.

Clinical significance of low-frequency mosaic thresholds (45,X/46,XX/47,XXX) in adulthood: A case report.

Taiwanese journal of obstetrics & gynecology2026 Mar

We present a distinction between age-related X chromosome loss and true mosaicism in women over 50 years of age and the clinical course in adulthood due to the low frequency of X chromosome dual aneuploidy. Clinical reports of adult women with the 45,X/46,XX/47,XXX karyotype are extremely rare. In a 51-year-old woman with short stature and schizophrenia with secondary amenorrhea shortly after the onset of her early menstrual period, the proportion of 45,X cell lines was 10 % by G-band and fluorescence in situ hybridization in the peripheral blood. The presence of 45,X in buccal mucosa cells and 47,XXX in peripheral blood suggests true mosaicism due to non-segregation in the early embryo rather than age-related X chromosome loss. This case supports the recent reports that a possible phenotypic effect exists at a 45,X cell threshold of 5 %.

Reproductive potential in mosaic Turner syndrome: impact of karyotype pattern and mosaicism ratio.

Climacteric : the journal of the International Menopause Society2026 Mar 10

This study aimed to evaluate reproductive potential in women with Turner syndrome (TS), focusing on 45,X/46,XX mosaicism and the impact of mosaic ratio on reproductive outcomes. The study retrospectively analyzed 145 TS patients diagnosed postnatally by peripheral blood karyotyping from January 1990 to May 2023. Karyotypes were categorized into 45,X monosomy, 45,X mosaicism with Y chromosome and 45,X mosaicism without Y chromosome. The predominant karyotype was 45,X/46,XX mosaicism (71.0%), accounting for most cases with preserved reproductive potential. Within this subgroup, spontaneous menarche (SM) occurred in 97.7% of cases with <40% 45,X cells, while 84.2% of pregnancies occurred in those with <10% 45,X cells. Among patients aged ≥15 years with mosaic karyotypes containing 46,XX and no structural abnormalities, SM occurred in 95.3% of those with <40% 45,X cells, but in none with ≥40% (p < 0.001). In contrast, cases of 45,X monosomy, Y-containing mosaicism, structural X abnormalities, 45,X/46,X with marker chromosomes or 45,X/47,XXX showed no pregnancies and minimal SM. Recurrent pregnancy loss (RPL) was the diagnostic indication in 34% of cases, likely enriching milder mosaicism. Women with 45,X/46,XX mosaicism retain reproductive potential, particularly when 45,X cell ratios are low. Early diagnosis via peripheral blood karyotyping supports timely fertility counseling and ovarian care. Turner syndrome (TS) is a genetic condition in females caused by the complete or partial loss of one sex chromosome. It can affect growth, development and fertility. Mosaicism refers to a condition where an individual has more than one genetically distinct cell line in their body, all derived from a single fertilized egg. In TS, this might mean that some cells are missing part or all of an X chromosome, while others carry different sex chromosome patterns like 46,XX, 47,XXX or other combinations. This study examined how different TS karyotypes, especially mosaic forms, relate to spontaneous menarche (SM) and pregnancy. We reviewed the records of 145 women diagnosed at a tertiary medical center in Taiwan. Most had mosaic TS without a Y chromosome. We found that patients with a lower percentage of 45,X cells were more likely to have SM and conceive. Among 53 women with pregnancy history, most had fewer than 10% of 45,X cells, although pregnancies were also seen in those with higher levels. In contrast, patients with non-mosaic TS or structural X abnormalities seldom had SM or achieved pregnancy. Our findings emphasize the value of detailed chromosome analysis and early counseling to support reproductive and hormonal health in women with TS. Early diagnosis and support can help improve reproductive planning and long-term care for women with TS.

Corneal biomechanics alterations and increased risk for corneal ectasia in Turner syndrome.

International ophthalmology2026 Mar 09

To assess corneal tomographic parameters and biomechanics of patients with Turner syndrome. Thirty-four eyes of 17 patients with Turner Syndrome (TS) and 20 eyes of 10 healthy females were evaluated for corneal parameters and biomechanics. The main outcome measures were anterior and posterior keratometry (K-meanAnt and K-meanPost) anterior and posterior elevation (AE, PE), central corneal thickness (CCT), anterior and posterior Q values (QAnt and QPost), corneal volume (CV), Belin-Ambrosio Tomographic Index (BAD), and biomechanical parameters such as Corneal Biomechanical Index (CBI), and Tomography-Biomechanical Index (TBI). The group of patients with TS was compared to a control group for all evaluated parameters. Significantly higher values of PE, CCT, CV, BAD, and TBI were observed in Turner Syndrome. The TS group displayed significantly lower K-meanPost, QAnt, and QPost values. BAD, CBI, and TBI values exceeding the cut off were observed in nine eyes (26.47%) in the TS group and three eyes (15%) in the control group. Patients with TS showed altered BAD values (odds ratio of 4.88). The TBI index was altered, with an odds ratio of 7.33, suggestive for significantly higher risk of ectasia. The CBI index was unvaried between groups. The cases with pathological BAD value were observed in individuals with mosaicism, suggesting a potential link between this karyotype and BAD alterations. Patients with TS exhibit altered biomechanical values indicating a significant risk for corneal ectasia. Periodic monitoring of corneal parameters in this population is necessary to detect early signs of ectasia.
