Variant summary
Our verdict is Likely benign. The variant received -2 ACMG points: 0P and 2B. BP4_Moderate
The NM_003900.5(SQSTM1):c.683C>T(p.Pro228Leu) variant causes a missense change. The variant allele was found at a frequency of 0.0000979 in 1,613,912 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 (★★). Synonymous variant affecting the same amino acid position (i.e. P228P) has been classified as Likely benign.

In silico analysis, which includes protein predictors and evolutionary conservation, supports a deleterious effect; Reported in a patient with sporadic amyotrophic lateral sclerosis in published literature (Fecto et al., 2011); Reported in a patient with frontotemporal lobar degeneration in published literature (van der Zee et al., 2014); This variant is associated with the following publications: (PMID: 22084127, 24899140, 24486447) -
Paget disease of bone 2, early-onset;C5779877:Frontotemporal dementia and/or amyotrophic lateral sclerosis 1 Uncertain:1
This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 228 of the SQSTM1 protein (p.Pro228Leu). This variant is present in population databases (rs151191977, gnomAD 0.01%). This missense change has been observed in individual(s) with sporadic amyotrophic lateral sclerosis and with frontotemporal lobar degeneration (PMID: 22084127, 24486447, 24899140). ClinVar contains an entry for this variant (Variation ID: 475402). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is not expected to disrupt SQSTM1 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. -
