Variant summary
Our verdict is Uncertain significance. Variant got 4 ACMG points: 5P and 1B. PM1PM2PP5BP4
The NM_000043.6(FAS):c.536T>G(p.Leu179Arg) 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 benign outcome for this variant. 12/20 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars).

Genes affected
FAS (HGNC:11920): (Fas cell surface death receptor) The protein encoded by this gene is a member of the TNF-receptor superfamily. This receptor contains a death domain. It has been shown to play a central role in the physiological regulation of programmed cell death, and has been implicated in the pathogenesis of various malignancies and diseases of the immune system. The interaction of this receptor with its ligand allows the formation of a death-inducing signaling complex that includes Fas-associated death domain protein (FADD), caspase 8, and caspase 10. The autoproteolytic processing of the caspases in the complex triggers a downstream caspase cascade, and leads to apoptosis. This receptor has been also shown to activate NF-kappaB, MAPK3/ERK1, and MAPK8/JNK, and is found to be involved in transducing the proliferating signals in normal diploid fibroblast and T cells. Several alternatively spliced transcript variants have been described, some of which are candidates for nonsense-mediated mRNA decay (NMD). The isoforms lacking the transmembrane domain may negatively regulate the apoptosis mediated by the full length isoform. [provided by RefSeq, Mar 2011]

Classification made for transcript
Verdict is Uncertain_significance. Variant got 4 ACMG points.
PM1
?
In a hotspot region, there are 2 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 1 benign, 5 uncertain in NM_000043.6
PM2
?
Very rare variant in population databases, with high coverage;
PP5
?
Variant 10-89010783-T-G is Pathogenic according to our data. Variant chr10-89010783-T-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 523313.We mark this variant Likely_pathogenic, oryginal submissions are: {Likely_pathogenic=2, Uncertain_significance=1}.
BP4
?
Computational evidence support a benign effect (MetaRNN=0.1901528). . Strength limited to SUPPORTING due to the PP5.

Autoimmune lymphoproliferative syndrome type 1 Pathogenic:1
Likely pathogenic, criteria provided, single submitter | clinical testing | Invitae | Jan 19, 2022 | 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. 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 expected to disrupt FAS protein function. ClinVar contains an entry for this variant (Variation ID: 523313). This missense change has been observed in individual(s) with autoimmune lymphoproliferative syndrome (ALPS) (Invitae). This variant is not present in population databases (gnomAD no frequency). This sequence change replaces leucine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 179 of the FAS protein (p.Leu179Arg). - |
