Variant summary
Our verdict is Likely benign. The variant received -5 ACMG points: 0P and 5B. BP4BS2
The ENST00000266732.8(TMPO):c.1405C>G(p.Leu469Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000044 in 1,614,082 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Synonymous variant affecting the same amino acid position (i.e. L469L) has been classified as Likely benign.

Loeys-Dietz syndrome 2 Uncertain:1
ClinVar contains an entry for this variant (Variation ID: 191793). This sequence change replaces leucine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 469 of the TMPO protein (p.Leu469Val). This variant is present in population databases (rs373861992, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with TMPO-related conditions. Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt TMPO protein function. 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. -
