Genetic testing of children with familial tall stature: is it worth doing?

Popis výsledku v původním jazyce

CONTEXT: Familial tall stature (FTS) is considered to be a benign variant of growth with a presumed polygenic etiology. However, monogenic disorders with possible associated pathological features could also be hidden under the FTS phenotype. OBJECTIVES: To elucidate the genetic etiology in families with FTS and to describe their phenotype in detail. DESIGN, SETTINGS AND PATIENTS: Children with FTS (height in both the child and his/her taller parent &gt;2 SD) referred to the Endocrinology center of Motol University Hospital were enrolled to the study. Their DNA was examined cytogenetically and via next-generation sequencing panel of 786 genes associated with growth. The genetic results were evaluated by the American College of Molecular Genetics and Genomics guidelines. All of the participants underwent standard endocrinological examination followed by specialized anthropometric evaluation. RESULTS: In total, 34 children (19 girls) with FTS were enrolled in the study. Their median height and their taller parent&apos;s height were 3.1 SD and 2.5 SD, respectively. The genetic cause of FTS was elucidated in 11/34 (32.4%) children (47, XXX and 47, XYY karyotypes, SHOX duplication, and causative variants in NSD1 [in 2], SUZ12 [in 2], FGFR3, CHD8, GPC3, and PPP2R5D genes). Ten children had absent syndromic sings and 24 had dysmorphic features. CONCLUSION: Monogenic (and cytogenetic) etiology of FTS can be found among children with FTS. Genetic examination should be considered in all children with FTS regardless of the presence of dysmorphic features.
