Genes affected

SLC35B3 (HGNC:21601): (solute carrier family 35 member B3) This gene is a member of the solute carrier family. The encoded protein is involved in the transport of 3-prime phosphoadenosine 5-prime phosphosulfate (PAPS) from the nucleus or the cytosol to the Golgi lumen. This gene has been reported to be expressed preferentially in the human colon tissues. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Dec 2013]

The c.899C>T (p.A300V) alteration is located in exon 9 (coding exon 8) of the SLC35B3 gene. This alteration results from a C to T substitution at nucleotide position 899, causing the alanine (A) at amino acid position 300 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
