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 GeneticsNov 18, 2022The c.1370C>G (p.T457S) alteration is located in exon 10 (coding exon 9) of the MAN1A1 gene. This alteration results from a C to G substitution at nucleotide position 1370, causing the threonine (T) at amino acid position 457 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
