A de novo paradigm for male infertility
Oud, M.S.; Smits, R.M.; Smith, H.E.; Mastrorosa, F.K.; Holt, G.S.; Houston, B.J.; de Vries, P.F.; Alobaidi, B.K.S.; Batty, L.E.; Ismail, H.De novo mutations are known to play a prominent role in sporadic disorders with reduced fitness. We hypothesize that de novo mutations play an important role in severe male infertility and explain a portion of the genetic causes of this understudied disorder. To test this hypothesis, we utilize trio-based exome sequencing in a cohort of 185 infertile males and their unaffected parents. Following a systematic an...
Variants in GCNA, X-linked germ-cell genome integrity gene, identified in men w...
Hardy, Jimmaline J.; Wyrwoll, Margot J.; Mcfadden, William; Malcher, Agnieszka; Rotte, Nadja; Pollock, Nijole C.; Munyoki, Sarah; Veroli, Maria V.Male infertility impacts millions of couples yet, the etiology of primary infertility remains largely unknown. A critical element of successful spermatogenesis is maintenance of genome integrity. Here, we present a genomic study of spermatogenic failure (SPGF). Our initial analysis (n=176) did not reveal known gene-candidates but identifed a potentially signifcant single-nucleotide variant (SNV) in X-linked ger...
Evaluation of the potential association of SOHLH2 polymorphisms with non-obstru...
Sánchez, Maria I.S.; Martín, Miriam C.; Egea, Rocío R.; Puchalt, Nicolás G.; Marco, Saturnino L.; Magraner, Gema R.; Ribeiro, SamuelNon-obstructive azoospermia (NOA) or spermatogenic failure is a complex disease with an important genetic component that causes infertility in men. Known genetic factors associated with NOA include AZF microdeletions of the Y chromosome or karyotype abnormalities; however, most causes of NOA are idiopathic. During the last decade, a large list of associations between single-nucleotide polymorphisms (SNP) and NO...
Hiperplasia Suprarrenal Congénita - importância da análise molecular no diagnós...
Gomes, Susana; Caetano, Iris; Silva, Júlia; Gonçalves, JoãoA hiperplasia suprarrenal congénita (CAH) é uma doença autossómica recessiva que ocorre devido a redução, mais ou menos pronunciada, da biossíntese suprarrenal de cortisol. Esta redução pode dever-se a defeitos enzimáticos da esteroidogénese os quais estão também associados a androgénios em excesso. A CAH mais frequente (~ 95% dos casos) deve-se a deficiência em 21-hidroxilase (21-OH, enzima codificada pelo gen...
