Description

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. Advanced modeling performed at Invitae incorporating data from internal and/or published experimental studies (Invitae) indicates that this missense variant is expected to disrupt TGFBR2 function. ClinVar contains an entry for this variant (Variation ID: 654639). This missense change has been observed in individual(s) with clinical features of TGFBR2-related conditions (PMID: 27879313; Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces serine, which is neutral and polar, with phenylalanine, which is neutral and non-polar, at codon 401 of the TGFBR2 protein (p.Ser401Phe).
