Genes affected

GALNT12 (HGNC:19877): (polypeptide N-acetylgalactosaminyltransferase 12) This gene encodes a member of a family of UDP-GalNAc:polypeptide N-acetylgalactosaminyltransferases, which catalyze the transfer of N-acetylgalactosamine (GalNAc) from UDP-GalNAc to a serine or threonine residue on a polypeptide acceptor in the initial step of O-linked protein glycosylation. Mutations in this gene are associated with an increased susceptibility to colorectal cancer.[provided by RefSeq, Mar 2011]

GALNT12 Gene-Disease associations (from GenCC):

• colorectal cancer, susceptibility to, 1

  Inheritance: Unknown, AD Classification: LIMITED Submitted by: ClinGen, Ambry Genetics, Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Benign. The variant received -15 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.37).
• BP6: Variant 9-98826885-C-T is Benign according to our data. Variant chr9-98826885-C-T is described in ClinVar as Likely_benign. ClinVar VariationId is 416217.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BP7: Synonymous conserved (PhyloP=-1.57 with no splicing effect.
• BS2: High AC in GnomAdExome4 at 31 AD,Unknown gene.
