Genes affected
PTCH2 (HGNC:9586): (patched 2) This gene encodes a transmembrane receptor of the patched gene family. The encoded protein may function as a tumor suppressor in the hedgehog signaling pathway. Alterations in this gene have been associated with nevoid basal cell carcinoma syndrome, basal cell carcinoma, medulloblastoma, and susceptibility to congenital macrostomia. Alternatively spliced transcript variants have been described.[provided by RefSeq, Oct 2009]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -6 ACMG points.

PP3
Multiple lines of computational evidence support a deleterious effect 7: AlphaMissense, BayesDel_noAF, Cadd, M_CAP, PROVEAN, REVEL, REVEL [when max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]
BP4
Computational evidence support a benign effect (MetaRNN=0.08204335).
BP6
Variant 1-44832296-A-G is Benign according to our data. Variant chr1-44832296-A-G is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 524629.
BS2
High AC in GnomAd4 at 13 AD,Unknown gene.
