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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 05, 2024The c.1378G>A (p.A460T) alteration is located in exon 10 (coding exon 9) of the MAN1A1 gene. This alteration results from a G to A substitution at nucleotide position 1378, causing the alanine (A) at amino acid position 460 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
