The boy had distinctive coarse facial features, widely spaced eyes (ocular hypertelorism), a large tongue (macroglossia), abnormal ears and abnormalities affecting the roof of the mouth (the palate). [abstracts.eurospe.org]

The main features pointing towards the diagnosis were macrosomia, coarse facial features and macroglossia with a midline groove in the tongue. Proband B developed a Wilms tumour. He was found to have a novel mutation causing a premature stop codon. [samj.org.za]

Simpson-Golabi-Behmel (SGB) syndrome is an X-linked recessive genetic disorder characterized by prenatal and postnatal overgrowth, coarse facial features, polydactyly and an increased risk of embryonal tumors. [ashg.org]

Female carriers are usually asymptomatic, but some are noted to have mild features detected following detailed clinical assessment after diagnosis in a male relative. [nature.com]

Carrier females are often asymptomatic, though females may also exhibit features of SGBS1. Genetic testing of GPC3 may confirm a diagnosis and help guide treatment and management decisions. [invitae.com]

Evaluation of relatives at-risk: It is appropriate to clarify the genetic status of apparently asymptomatic older and younger at-risk relatives of an affected individual by molecular genetic testing of the GPC3 or GCP4 pathogenic variant in the family [ncbi.nlm.nih.gov]

Simpson Golabi Behmel Syndrome (SGBS) is an X-linked overgrowth syndrome with coarse craniofacial features that include hypertelorism, epicanthal folds, macrostomia, macroglossia, and antiverted nares. [oxfordmedicine.com]

Major clinical findings include early onset intractable epileptic encephalopathy with a burst-suppression pattern on EEG, generalized muscular hypotonia, structural brain abnormalities, macrocephaly and increased birth weight, joint contractures, coarse [zora.uzh.ch]

Neurologic manifestations are perhaps the most varied findings. Hypotonia and absent primitive reflexes, a high-pitched cry in neonates, seizures, and abnormal EEG have all been described. [ncbi.nlm.nih.gov]
