<span class="mim-text-font">
<p>By EST database searching with the S. cerevisiae MT I gene (ALG1) and subsequent screening of a human fetal brain cDNA library, Takahashi et al. (2000) isolated a cDNA corresponding to the human homolog, which they called HMAT1. HMAT1 encodes a 464-amino acid protein that shares 36% amino acid identity with the S. cerevisiae and C. elegans gene products. HMAT1 contains a hydrophobic region at the N terminus followed by short hydrophilic and hydrophobic regions. Takahashi et al. (2000) demonstrated that HMAT1 complemented the temperature-sensitive phenotype of a yeast strain lacking functional MT I due to an ALG1 mutation, indicating that the function of this enzyme is conserved between yeast and human. </p>

<p>In patients with congenital disorder of glycosylation type Ik (608540), Schwarz et al. (2004) and Kranz et al. (2004) identified mutations in the ALG1 gene (605907.0001-605907.0002). </p><p>Grubenmann et al. (2004) used a fluorescent method to detect accumulation of dolichylpyrophosphate-GlcNAc2 in a previously untyped CDG patient. The accumulation pattern suggested a deficiency of the ALG1 beta-1,4 mannosyltransferase. Sequence analysis identified compound heterozygosity for 2 mutations in the ALG1 gene (see 605907.0003). </p><p>In 5 unrelated French patients with CDG type Ik, Dupre et al. (2010) identified homozygous or compound heterozygous mutations in the ALG1 gene, including 7 novel mutations (see, e.g., 605907.0004-605907.0007). The phenotype was severe, with neurologic impairment in all patients and dysmorphic features in 4. </p><p>In a patient with CDG Ik and nephrotic syndrome, Harshman et al. (2016) identified homozygosity for the previously identified S258L mutation in the ALG1 gene (605907.0001). The mutation was found by whole-exome sequencing and confirmed by Sanger sequencing. </p>

To ensure long-term funding for the OMIM project, we have diversified
our revenue stream. We are determined to keep this website freely
accessible. Unfortunately, it is not free to produce. Expert curators
review the literature and organize it to facilitate your work. Over 90%
of the OMIM's operating expenses go to salary support for MD and PhD
science writers and biocurators. Please join your colleagues by making a
donation now and again in the future. Donations are an important
