Variant summary
Our verdict is Likely benign. Variant got -1 ACMG points: 3P and 4B. PM2PP2BP4_Strong
The NM_000264.5(PTCH1):c.4081G>T(p.Val1361Leu) 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. 16/21 in silico tools predict 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. V1361M) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Jun 28, 2019 | The p.V1361L variant (also known as c.4081G>T), located in coding exon 23 of the PTCH1 gene, results from a G to T substitution at nucleotide position 4081. The valine at codon 1361 is replaced by leucine, an amino acid with highly similar properties. This amino acid position is poorly conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. - |
