Myhre syndrome in adulthood: clinical variability and emerging genotype-phenotype correlations.

Myhre syndrome (MS, MIM 139210) is a rare multisystemic disorder caused by recurrent pathogenic missense variants in SMAD4. The clinical features have been mainly documented in childhood and comprise variable neurocognitive development, recognizable craniofacial features, a short stature with a pseudo-muscular build, hearing loss, thickened skin, joint limitations, diverse cardiovascular and airway manifestations, and increased fibrosis often following trauma or surgery. In contrast, adults with MS are underreported obscuring potential clinical variability.

Incidence of and indications for sperm donor restriction - analysis of patients continuing treatment: a retrospective single-centre study.

Research Question: What are the incidence of and indications for sperm donor restriction due to suspected/confirmed disease risk, and the future treatment choices of patients using these sperm donors?

Design: This single-centre retrospective study involved donors who had restrictions on the use of their imported spermatozoa from January 2010 to December 2019, and current or previous recipients. Indications for sperm restriction and the characteristics of patients undergoing medically assisted reproduction (MAR) treatment with these specimens at the time of restriction were collected. Differential characteristics of women who decided on whether or not to contintue the procedure were assessed.
