Hum Mol Genet. 2020 Aug 3;29(13):21482161. doi: doi:10.1093/hmg/ddaa100. https://www.ncbi.nlm.nih.gov/pubmed/32452519This study explores the hitherto unknown role of FGF9 in human testis development. The authors use two mouse models that phenocopy the skeletal defects of dominant FGF9 mutations that cause skelet...

Proc Natl Acad Sci USA. 2020 Jun 16;117(24):1368013688. 10.1073/pnas.1921676117. PMID: 32493750.On the search for a genetic cause for 46,XX virilization due to testicular (TDSD) or ovotesticular DSD (OTDSD), 78 individuals were studied by whole exome sequencing. In 7 cases, heterozygous de novo variants were found in the 4th zinc finger (ZF4) of the Wilms tumor 1 gene (<em...

Int J Mol Sci. 2020 Nov 9;21(21):8403. doi: 10.3390/ijms21218403. PMID: 33182400This case report describes a patient with clinically diagnosed partial androgen insensitivity syndrome (PAIS). However, no mutation in the androgen receptor gene was identified. Instead, whole genome sequencing revealed a heterozygous point mutation inherited from the mother in the FKBP4 gene. This gene i...

Int J Mol Sci. 2020 Sep 10;21(18). pii: E6614. doi: 10.3390/ijms21186614. PMID: 32927658This review first summarises current molecular knowledge of gonadal development and related DSDs, and then overviews methods of single-cell sequencing (sc-seq) technologies and their applications and findings for healthy gonads and disease states. Recent studies are listed in two tables and major findings ...
