Ring Chromosome 4 in a Child with Multiple Congenital Abnormalities: A Case Report and Review of the Literature

Abstract: A female child born preterm with intrauterine growth retardation and presenting with facial dysmorphism with clefts, microcephaly, limb deformities, and congenital abnormalities involving cardiovascular and urinary systems is described. Chromosomal analysis showed a de novo 46,XX,r(4)(p15.3q35) karyotype. The clinical features of the patient were compared with the phenotypic characteristics of 17 previously reported cases with ring chromosome 4 and those with Wolf-Hirschhorn syndrome (4p-). Clinical features o… Show more

“…Ring chromosomes are rare structural abnormalities, usually resulting because of breakage of the distal segments of the short and long arms, with subsequent end joining. Almost all reported ring chromosome 4 patients had both prenatal and postnatal growth retardation and microcephaly, developmental delay and intellectual disability (Balci et al, 2006; Concolino et al, 2007; Paththinige et al, 2016). Both of our ring chromosome female patients (patients 9 and 10) had dysmorphic features with the characteristic facial appearance and a global developmental delay.…”
