Genes affected
DPYSL5 (HGNC:20637): (dihydropyrimidinase like 5) This gene encodes a member of the CRMP (collapsing response mediator protein) family thought to be involved in neural development. Antibodies to the encoded protein were found in some patients with neurologic symptoms who had paraneoplastic syndrome. A pseudogene of this gene is found on chromosome 11. Multiple alternatively spliced variants, encoding the same protein, have been identified. [provided by RefSeq, Dec 2011]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2022The c.445G>A (p.V149M) alteration is located in exon 4 (coding exon 3) of the DPYSL5 gene. This alteration results from a G to A substitution at nucleotide position 445, causing the valine (V) at amino acid position 149 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
