Genes affected

MAN1A1 (HGNC:6821): (mannosidase alpha class 1A member 1) This gene encodes a class I mammalian Golgi 1,2-mannosidase which is a type II transmembrane protein. This protein catalyzes the hydrolysis of three terminal mannose residues from peptide-bound Man(9)-GlcNAc(2) oligosaccharides and belongs to family 47 of glycosyl hydrolases.

The c.929T>C (p.V310A) alteration is located in exon 6 (coding exon 5) of the MAN1A1 gene. This alteration results from a T to C substitution at nucleotide position 929, causing the valine (V) at amino acid position 310 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
