Popis: | Biallelic loss of function of TELO2 gene cause a severe syndromic disease mainly characterized by global developmental delay with poor motor and language acquisitions, microcephaly, short stature, minor facial and limbs anomalies, sleep disorder, spasticity, and balance impairment up to ataxia. TELO2-related syndrome, also known as You-Hoover-Fong Syndrome, is extremely rare and since its first description in 2016 only 8 individuals have been reported, all showing a severe disability. The causative gene is member of the big molecular family of genes responsible for cells proliferation and DNA stability. We describe the case of two sisters, carrying the homozygous p. Arg609His variant of the gene, who present a milder phenotype of TELO2-related syndrome. Such variant has been reported once in a more severely affected patient, in compound heterozygous state associated with the p. Pro260Leu variant, suggesting a possible role of the p. Arg609His variant in determining milder phenotypes. Comparing the siblings with all previously reported cases, we offer an overview on the condition and discuss TELO2 genetic interactions, in order to further explore the molecular bases of this recently described disorder. |
