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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 08, 2024The c.163C>A (p.R55S) alteration is located in exon 1 (coding exon 1) of the RPRM gene. This alteration results from a C to A substitution at nucleotide position 163, causing the arginine (R) at amino acid position 55 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
