βΈ» 🧬 JUST PUBLISHED! Our latest meta-analysis is out in the American Journal of Medical Genetics – Part A! We compared the diagnostic yield of genome sequencing (WGS) vs exome reanalysis (WES) in children with rare diseases. πŸ‘‡ πŸ”— doi.org/10.1002/ajmg.a…

πŸ‘ΆπŸ½ We analyzed over 1600 children with negative exome sequencing results to evaluate which strategy performs better for uncovering genetic diagnoses. πŸ“Œ Key findings: β€’ WGS provided an additional diagnosis in 7% of cases β€’ WES reanalysis achieved a 14.2% diagnostic yield

πŸ’‘ What does it mean in practice? WGS can serve as a valuable complementary tool, especially after a negative exome. Yet periodic reanalysis of WES remains an effective and more accessible option in many settings.

🧬 Male infertility & genetics at #ESHRE2025: 300 genes linked to male infertility, but only 104 have strong evidence for clinical panels. New data on globozoospermia, CFTR-related obstruction & exome insights in NOA. Game-changing advances! #Andrology #Genomics #Fertility

πŸ”¬ Genetics & early pregnancy loss at #ESHRE2025! In a brilliant precongress session, Prof. Andres Salumets shared how genomic aberrations, maternal age, and microbial dysbiosis are key factors in miscarriage. Non-invasive POC analysis & BEVs are emerging tools to watch! πŸ“Paris

#ESHREJC organised Scientific Speed Dating, as you can see in video and voice people are getting new connections with Junior and Senior colleagues from field. Great event #eshrejc. The ESHRE 5 ESHRE

πŸ“ Live from #ESHRE2025 In Andres Salumets’ session, genetics took center stage in 1st trimester pregnancy loss: πŸ”¬ 60% of POCs show chromosomal abnormalities πŸ§“ Maternal age = key risk factor 🧬 Up to 90% of IVF embryos are mosaic πŸ§ͺ cfDNA & dysbiosis = promising frontiers

πŸ”¬ At #ESHRE2025, Dr. Olga Tsiuko (UZ Leuven) presented a powerful comparison of WGS vs SNP-array & GBS-RRS in PGT. βœ… WGS stands out in: β€’Resolution (SNVs, indels, CNVs) β€’PGT-M, PGT-A & PGT-SR accuracy β€’Detection of de novo mutations β€’Emerging use in polygenic risk scores

🧬 From the first IVF baby to WGS replacing SNP-array in PGT, here’s what’s new: πŸ”Ή WGS = true all-in-one: PGT-M, PGT-AO, PGT-SR, mtDNA πŸ”Ή Detects aneuploidies, translocations & de novo variants πŸ”Ή 5–10x coverage enough for most variants; 30x for de novo

🚨 New paper out! We conducted a systematic review & meta-analysis on idebenone for LHON (Leber hereditary optic neuropathy) and found a significant visual benefit (mean LogMAR βˆ’0.32). Proud to be first author! 🧬 Published in Ophthalmic Genetics πŸ”— doi.org/10.1080/138168…

Paulo Victor Zattar Ribeiro (@drpaulogen) 's Twitter Profile Photo

Our meta-analysis (5 studies, 375 pts) showed that idebenone significantly improves visual acuity in LHON (LogMAR gain βˆ’0.32; 95% CI βˆ’0.50 to βˆ’0.15). ⬆️ Equivalent to ~1.5–5 lines on the visual scale!
