GeneReviews. Proliferating chondrocytes secrete extracellular matrix (ECM) components to support the bone structure, while hypertrophic chondrocytes apoptose and promote osteoblast influx responsible for bone mineralization. Macrocephaly usually denotes a head circumference greater than the 97th percentile. Genetic testing can be done via blood or saliva test and usually takes 26 weeks to result, depending on the type of test. Genet Med. Couples utilizing ART should therefore be informed about the increased risk.

This causes the maternal allele to function similar to the paternal allele, resulting in overgrowth with macroglossia. She has been receiving physical therapy since age 6 months due to hypotonia and also speech therapy for expressive language delays. The development of growth references and growth charts. The fetal head circumference to abdominal circumference ratio is below the 3 rd percentile (2 standards deviations below the normal mean for gestational age). Existence of one cardinal feature such as macroglossia, lateralized growth, multifocal or bilateral Wilms tumor, or persistent hypoglycemia merits genetic testing, while 2 of these symptoms can establish a clinical diagnosis. doi: 10.1002/humu.23563, 69.

Most mutations causing Sotos syndrome are point mutationschanges in the sequence that substitute one amino acid with another (missense variant) or causing early termination of transcription (non-sense). (2012) 39:38294. doi: 10.1097/01.GIM.0000178503.15559.d3. IC1, imprinting center 1, attracts the non-methylated form CTCF (transcription repressors of the CCCTC-binding family), which activates transcription of H19, a non-coding RNA, which represses growth. Both have normal intellect, prenatal overgrowth, and both presented with malignant bone tumors. Macrocephaly is seen with other overgrowth syndrome, including Sotos, Weaver, and familial cases, however, when presented with either benign cutaneous growth (Cowden syndrome), very severe macrocephaly, penile macules (Bannayan-Riley-Ruvalcaba), or with autism, it is suggestive of PHTS and warrants a referral to geneticist for further evaluation. doi: 10.1002/aur.1266, 20.
