Variant summary
Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate
The ENST00000359593.9(AP4M1):c.1100G>A(p.Arg367Gln) variant causes a missense change. The variant allele was found at a frequency of 0.000351 in 1,613,738 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R367W) has been classified as Uncertain significance.

Uncertain significance, criteria provided, single submitter | clinical testing | Labcorp Genetics (formerly Invitae), Labcorp | Jan 25, 2024 | This sequence change replaces arginine, which is basic and polar, with glutamine, which is neutral and polar, at codon 367 of the AP4M1 protein (p.Arg367Gln). This variant is present in population databases (rs139861201, gnomAD 0.05%). This missense change has been observed in individual(s) with hereditary spastic paraplegia (PMID: 32979048). ClinVar contains an entry for this variant (Variation ID: 386884). 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 AP4M1 protein function with a negative predictive value of 80%. 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. - |
