Genes affected

NEU4 (HGNC:21328): (neuraminidase 4) The protein encoded by this gene belongs to a family of glycohydrolytic enzymes, which remove terminal sialic acid residues from various sialo derivatives, such as glycoproteins, glycolipids, oligosaccharides, and gangliosides. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Nov 2009]

Ambry Genetics

Jul 20, 2021

The c.256G>A (p.V86M) alteration is located in exon 3 (coding exon 3) of the NEU4 gene. This alteration results from a G to A substitution at nucleotide position 256, causing the valine (V) at amino acid position 86 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
