Deletions over … (more) The copy number loss of 12q14.3q15 involves multiple coding genes, including HMGA2 (OMIM 600698), and is expected to cause phenotypic and/or developmental abnormalities. Deletions over this region of variable sizes affecting HMGA2 have been reported in the literature in patients with Silver-Russell syndrome-5 (OMIM 618908), a genetic disorder characterized by variable developmental disorders, intrauterine growth retardation with feeding difficulties in early childhood and postnatal growth failure, and dysmorphic features (Mercadante et al., Ital J Pediatr. 2020 Jul 28;46(1):108. PMID: 32723361). HMGA2 deletion is implicated for its role in growth regulation. Patients with focal deletions of HMGA2 have similar phenotypic features that include pre- and postnatal growth failure and underweight (Crescenzo et al., J Hum Genet. 2015 Jun;60(6):287-93.
