Variant summary
Our verdict is Uncertain significance. Variant got 3 ACMG points: 5P and 2B. PM1PM2PP2BP4BP6
The NM_000368.5(TSC1):c.1571C>T(p.Ser524Phe) variant causes a missense change. The variant allele was found at a frequency of 0.00000124 in 1,614,032 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 Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S524A) has been classified as Uncertain significance.

Hereditary cancer-predisposing syndrome Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jan 08, 2024 | The p.S524F variant (also known as c.1571C>T), located in coding exon 13 of the TSC1 gene, results from a C to T substitution at nucleotide position 1571. The serine at codon 524 is replaced by phenylalanine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
