Pierpont syndrome: report of a new patient
We report on a male child with developmental delay, distinctive facial dysmorphic features, dystrophy, and abnormal fat distribution in the feet, in whom we identified the identical TBL1XR1 mutation. This patient also had additional clinical features including microphthalmia, pendular nystagmus, cryptorchidism, dermal sinus, and peripheral joint laxity, which had not been reported previously in association with Pierpont syndrome. This patient corroborates the assumption that Pierpont syndrome is exclusively caused by the specific TBL1XR1 missense mutation p.(Tyr446Cys) and the additional features broaden the phenotypic spe...

Marfanoid habitus is a nonspecific feature of Perrault syndrome
The objective of this study was to report the clinical and biological characteristics of two Perrault syndrome cases in a Moroccan family with homozygous variant c.1565C>A in the LARS2 gene and to establish genotype–phenotype correlation of patients with the same mutation by review of the literature. Whole-exome sequencing was performed. Data analysis was carried out and confirmed by Sanger sequencing and segregation. The affected siblings were diagnosed as having Perrault syndrome with sensorineural hearing loss at low frequencies; the female proband had primary amenorrhea and ovarian dysgenesis. Both affected individua...

RAF1 variants causing biventricular hypertrophic cardiomyopathy in two preterm infants: further phenotypic delineation and review of literature
We present two premature neonates with progressive biventricular hypertrophy found to have RAF1 variants in the CR2 domain. Molecular testing in patient 1 revealed a missense variant of a highly conserved residue c.782 C>G (p.P261R). This variant has been reported once with fatal outcome. Patient 2 also had a missense variant in a highly conserved neighboring residue c.770 C>T (p.S257L). This variant has been previously reported, most recently associated with the development of pulmonary arterial hypertension. Both our patients had prenatal findings of polyhydramnios, short long bones, hydrops fetalis, and cardiac anomalie...
