Genes affected

RPRM (HGNC:24201): (reprimo, TP53 dependent G2 arrest mediator homolog) Predicted to be involved in regulation of mitotic cell cycle. Predicted to act upstream of or within regulation of cell cycle. Predicted to be integral component of membrane. Predicted to be active in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

GALNT13 (HGNC:23242): (polypeptide N-acetylgalactosaminyltransferase 13) The GALNT13 protein is a member of the UDP-N-acetyl-alpha-D-galactosamine:polypeptide N-acetylgalactosaminyltransferase (GalNAcT; EC 2.4.1.41) family, which initiate O-linked glycosylation of mucins (see MUC3A, MIM 158371) by the initial transfer of N-acetylgalactosamine (GalNAc) with an alpha-linkage to a serine or threonine residue.[supplied by OMIM, Apr 2004]

ENSG00000227400 (HGNC:):

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.
