Classification rationale
1

The PTCH1 NM_000264.5:c.-9_-4del (NP_000255.2:p.?) variant has been reported in ClinVar, where current submissions classify it as benign or likely benign.

This variant is common in population databases, with an allele frequency of 1.31180% in gnomAD v4.1, 0.75389% in gnomAD v2.1, and 1.26862% in gnomAD-Canada, which is above the non-VCEP BA1 benign threshold of 1%.
