Genes affected

ENTREP3 (HGNC:1233): (endosomal transmembrane epsin interactor 3) This gene is located near the gene for the lysosomal enzyme glucosylceramidase; a deficiency in this enzyme is associated with Gaucher disease. The encoded protein has been identified as a potential binding partner of a WW domain-containing protein which is involved in apoptosis and tumor suppression. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2010]

The c.1936C>T (p.R646C) alteration is located in exon 12 (coding exon 12) of the FAM189B gene. This alteration results from a C to T substitution at nucleotide position 1936, causing the arginine (R) at amino acid position 646 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
