Variant summary
Our verdict is Benign. The variant received -7 ACMG points: 0P and 7B. BP4_ModerateBP6BS2
The NM_000264.5(PTCH1):c.3748C>T(p.Pro1250Ser) variant causes a missense change. The variant allele was found at a frequency of 0.00000558 in 1,614,084 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict 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. P1250R) has been classified as Uncertain significance.

Basal cell carcinoma, susceptibility to, 1 Uncertain:1

Hereditary cancer-predisposing syndrome Uncertain:1
The p.P1250S variant (also known as c.3748C>T), located in coding exon 22 of the PTCH1 gene, results from a C to T substitution at nucleotide position 3748. The proline at codon 1250 is replaced by serine, an amino acid with similar properties. This amino acid position is well 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. -
