Sangavi Sivagnanasundram (Melbourne Health)
TIMES syndrome is a multisystem disorder characterised by considerable phenotypic variability, but overlapping features include telangiectasia, impaired intellectual development, microcephaly, metaphyseal dysplasia, eye abnormalities, and short stature. Patients exhibit striking cutis marmorata in infancy.
Two individuals from unrelated families presenting with similar features consistent with TIMES syndrome.
Leu400IlefsTer8 and Val390Leu variants were identified however the proposed mechanism of disease is GoF.
Supporting in vitro functional assay was conducted however further evidence is required to upgrade the gene classification.
