Variant summary

Our verdict is Benign. The variant received -7 ACMG points: 2P and 9B. PM2 BP4_Strong BP7 BS2

The NM_003738.5(PTCH2):​c.3216T>G​(p.Gly1072Gly) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000342 in 1,461,886 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. G1072G) has been classified as Benign.

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

Our verdict: Benign. The variant received -7 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.65).
• BP7: Synonymous conserved (PhyloP=-0.793 with no splicing effect.
• BS2: High AC in GnomAdExome4 at 5 AD,Unknown gene.
