Intellectual disability syndromic and non-syndromic v0.5661 MAX Rylee Peters gene: MAX was added
gene: MAX was added to Intellectual disability syndromic and non-syndromic. Sources: Literature
Mode of inheritance for gene: MAX was set to MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Publications for gene: MAX were set to 38141607
Phenotypes for gene: MAX were set to Syndromic disease (MONDO:0002254), MAX-related
Review for gene: MAX was set to GREEN
Added comment: Three individuals who each share a recurrent de novo germline variant in the MAX gene, resulting in a p.Arg60Gln substitution in the loop of the b-HLH-LZ domain.

Affected individuals have a complex disorder consisting primarily of macrocephaly, polydactyly, and delayed ophthalmic development. Other phenotypes reported include intellectual disability, perianal abscesses, pectus carinatum, hypospadias, renal agenesis, single umbilical artery, flattened thoracic vertebrae.

Functional analysis of the p.Arg60Gln variant shows a significant increase in CCND2 protein and a more efficient heterodimerization with c-Myc resulting in an increase in transcriptional activity of c-Myc.
