Abstract

The most cases of persistence hyperplastic primary vitreous (PHPV) are unilateral and sporadic, however, bilateral presentation could be present in a small number of patients, in whom other genetic diseases must be ruled out. We describe a case of a 2 months child with bilateral persistence hyperplastic primary vitreous confirmed by ultrasound. In addition, with neurodevelopmental defects, microcephaly, facial dimorphism, axial hypotonia, and without brain abnormalities on MRI, in whom a de novo mutation of the CTNNB1 gene was found during the genetic study, which explains the findings.

Keywords:
CTNNB1 gene
Microphthalmia
Microcephaly
Persistent fetal vasculature
Persistence hyperplastic primary vitreous
Developmental disabilities
Resumen

La mayoría de los casos de persistencia de la vasculatura fetal (PVF) o persistencia del vitreo primario hiperplásico (PVPH) son de naturaleza unilateral y esporádica, sin embargo, podría tener presentación bilateral en un pequeño número de pacientes, en los cuales deben descartarse enfermedades genéticas. Describimos un caso de un lactante de 2 meses en quien se observó hiperplasia del vitreo primario bilateral confirmada por ecografía. Además, cursaba con defectos del neurodesarrollo, microcefalia, dimorfismo facial, hipotonía axial, sin alteraciones cerebrales en resonancia magnética. En el estudio genético se encontró mutación de novo del gen CTNNB1, que explica los hallazgos.

Palabras clave:
