Variant summary
Our verdict is Likely pathogenic. Variant got 9 ACMG points: 9P and 0B. PM1PM2PM5PP3PP5_Moderate
The NM_001099274.3(TINF2):c.850A>G(p.Thr284Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Likely pathogenic (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T284K) has been classified as Uncertain significance.

Dyskeratosis congenita Pathogenic:1
Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Mar 22, 2022 | This sequence change replaces threonine, which is neutral and polar, with alanine, which is neutral and non-polar, at codon 284 of the TINF2 protein (p.Thr284Ala). This variant is not present in population databases (gnomAD no frequency). In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C55"). ClinVar contains an entry for this variant (Variation ID: 38923). This missense change has been observed in individual(s) with clinical features of dyskeratosis congenita (PMID: 18669893; Invitae). In at least one individual the variant was observed to be de novo. - |
