About 50% of Lamp2-deficient animals died between postnatal days 20 and 40, independent of sex and genetic background (C57B6/Jx129SV and 129SV). In addition, Lamp2-deficient mice were smaller than wildtype mice. Surviving mice were fertile and had an almost normal life span. Ultrastructurally, there was extensive accumulation of autophagic vacuoles in many tissues, including liver, pancreas, spleen, kidney, and skeletal and heart muscle. In hepatocytes, the autophagic degradation of long-lived proteins was severely impaired. Cardiac myocytes were ultrastructurally abnormal and heart contractility was severely reduced. These findings indicated that LAMP2 is critical for autophagy. This theory was further substantiated by the finding that human LAMP2 deficiency, which causes Danon disease, is associated with the accumulation of autophagic material in striated myocytes. <a href="https://pubmed.ncbi.nlm.nih.gov/?cmd=link&linkname=pubmed_pubmed&from_uid=10972293" target="_blank" onclick="gtag('event', 'mim_outbound', {'name': 'PubMed Related', 'domain': 'pubmed.ncbi.nlm.nih.gov'})"><span class="glyphicon glyphicon-plus-sign mim-tip-hint" title="Click this 'reference-plus' icon to see articles related to this paragraph in PubMed."></span></a></p>

<strong>Description</strong>

<span class="mim-text-font">
<p>The lysosomal membrane plays a vital role in the function of lysosomes by sequestering numerous acid hydrolases that are responsible for the degradation of foreign materials and for specialized autolytic functions. LAMP1 (153330) and LAMP2 are glycoproteins that constitute a significant fraction of the total lysosomal membrane glycoproteins. Both consist of polypeptides of about 40 kD, with 16 to 20 N-linked saccharides attached to the core polypeptides (Fukuda et al., 1988). </p>

<strong>Cloning and Expression</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>Fukuda et al. (1988) isolated human cDNAs encoding LAMP1 and LAMP2. </p><p>Using mouse Lgp110 to screen a human liver cDNA library, Konecki et al. (1994) cloned LAMP2. Sequencing analysis indicated that there are 4 polyadenylation signals in the 3-prime UTR, with the second being the most frequently used. The deduced 410-amino acid protein contains a leader sequence; a luminal domain consisting of 2 homologous domains with 4 identically spaced cysteines linked by 2 disulfide bonds; a 20-amino acid transmembrane region; and a short cytoplasmic tail containing the lysosomal membrane targeting signal. The protein is heavily N-glycosylated. </p><p>By screening human liver and pheochromocytoma cDNA libraries, Konecki et al. (1995) identified a LAMP2 variant, which they called LAMP2B, that results from alternative splicing of exon 9. They designated the variant reported by Konecki et al. (1994) as LAMP2A. The deduced LAMP2B protein contains 410 amino acids, like the LAMP2A protein, but its C-terminal sequence differs in the last 11 amino acids of the luminal domain, the transmembrane domain, and the cytoplasmic tail. LAMP2B retains the lysosomal targeting signal, gly-tyr-x-x, and has the same number of potential glycosylation sites as LAMB2A. The LAMP2B variant has 3 polyadenylation signals in the 3-prime UTR. Using a common 5-prime LAMP2 sequence as probe for Northern blot analysis, Konecki et al. (1995) identified 6 major LAMP2 transcripts in liver and 4 major transcripts in pheochromocytoma mRNA. By Northern blot analysis using LAMP2B-specific probes, they detected highest expression of LAMP2B in skeletal muscle, with very low expression in liver. LAMP2B was also expressed in fibroblasts and fetal liver. Northern blot analysis using LAMP2A-specific probes detected highest LAMP2A expression in placenta, lung, and liver, with much lower expression in skeletal muscle. Immunoelectron microscopy localized LAMP2 primarily on the luminal side of endocytic organelles. No labeling of the plasma membrane was observed. </p>

<strong>Gene Function</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>LAMP2 is thought to protect the lysosomal membrane from proteolytic enzymes within lysosomes and to act as a receptor for proteins to be imported into lysosomes (Fukuda, 1994). </p><p>Kain et al. (2008) found that virtually all individuals with pauci-immune focal necrotizing glomerulonephritis (FNGN) had autoantibodies against LAMP2 and that autoantibodies against LAMP2 caused this disease when injected into rats. A monoclonal antibody to human LAMP2 induced apoptosis of human microvascular endothelium in vitro. The autoantibodies in individuals with pauci-immune FNGN commonly recognize a human LAMP2 epitope with 100% homology to the bacterial adhesin FimH, with which they crossreact. Rats immunized with FimH developed pauci-immune FNGN and also developed antibodies to rat and human LAMP2. Finally, Kain et al. (2008) showed that infections with fimbriated pathogens are common before the onset of FNGN. Thus, Kain et al. (2008) concluded that FimH-triggered autoimmunity to LAMP2 provides a previously undescribed clinically relevant molecular mechanism for the development of pauci-immune FNGN. </p>

<strong>Gene Structure</strong>

<strong>Mapping</strong>
</span>
</h4>
</div>
<span class="mim-text-font">
<p>By in situ hybridization, Mattei et al. (1990) mapped the LAMP2 gene to Xq24-q25. This was taken to support the view that LAMP1 and LAMP2 diverged relatively early in evolution and that they have distinct functions which emerged as soon as eukaryotic cells acquired lysosomes as subcellular compartments. </p><p>Isolation and identification of human genes can be helped by isolation of cDNA clones, identification of DNA fragments conserved in distant species, and direct sequence analysis. Identification of CpG islands is an additional tool. CpG islands, unmethylated tracts of DNA that are 0.5 to 2 kb long and very rich in G+C and in the dinucleotide CpG, are located in the 5-prime region of all sequenced housekeeping genes and of many tissue-specific genes (Bird, 1987). The lack of methylation of CpG islands makes them a preferential site of cleavage for methylation-sensitive restriction enzymes with one or more CpGs in their recognition site, such as HpaII, EagI, SacII, BssHII, and NotI. Lindsay and Bird (1987) demonstrated the usefulness of CpG islands as landmarks for identifying genes. In an EagI-EcoRI library of the distal long arm of the human X chromosome, Manoni et al. (1991) found a clone that mapped to Xq24 (by hybridization with a panel of human-hamster cell hybrids carrying deletions of different portions of the human X chromosome between Xq24 and Xqter). Using Southern hybridization and hamster/human hybrid cell panels, Schleutker et al. (1991) confirmed the localization of the LAMP2 gene on the X chromosome. In the course of high-resolution comparative mapping of the proximal region of the mouse X chromosome, Blair et al. (1995) demonstrated the location of the Lamp2 gene in relation to others. </p>

<span class="mim-text-font">
<p>In 10 patients with Danon disease (300257), Nishino et al. (2000) identified mutations in the LAMP2 gene (see, e.g., 309060.0001-309060.0006). </p><p>Charron et al. (2004) analyzed the LAMP2 gene in 50 patients diagnosed with hypertrophic cardiomyopathy (CMH; see 192600) who were negative for mutations in 9 sarcomeric genes and did not have autosomal dominant inheritance. The authors identified 2 different mutations in the LAMP2 gene (309060.0008 and 309060.0009)in 2 patients, both of whom had skeletal muscle weakness on examination and PAS-positive sarcoplasmic vacuoles on skeletal muscle biopsy by light microscopy. </p><p>LAMP2 mutations typically cause multisystem Danon disease, which can also present as a primary cardiomyopathy. In genetic analyses of 24 subjects with increased left ventricular wall thickness and electrocardiogram suggesting ventricular preexcitation, Arad et al. (2005) found 4 LAMP2 mutations (see, e.g., 309060.0010) and 7 PRKAG2 (602743) mutations. Clinical features associated with defects in LAMP2 included male sex, severe hypertrophy, early onset (at 8 to 17 years of age), ventricular preexcitation, and asymptomatic elevations of 2 serum proteins. Mutations in heterozygous state appeared to be responsible for unusual heart disease in some females. </p><p>In a family (XLCM-2) that presented with dilated cardiomyopathy and was linked to the dystrophin gene (300377) by Towbin et al. (1993), Taylor et al. (2007) identified a mutation in the LAMP2 gene (309060.0012), confirming a diagnosis of Danon disease. </p><p>Roos et al. (2018) identified hemizygosity or heterozygosity for a splicing mutation in the LAMP2 gene (309060.0013) in 4 males and 3 females from a family with variable features of Danon disease. LAMP2 expression was decreased in fibroblasts from the proband. </p>

<strong>Animal Model</strong>

</div>
<span class="mim-text-font">
<p>Tanaka et al. (2000) generated mice deficient in Lamp2 by targeted disruption. Lamp2 knockout mice showed elevated mortality and reduced weight compared with their wildtype littermates. About 50% of Lamp2-deficient animals died between postnatal days 20 and 40, independent of sex and genetic background (C57B6/Jx129SV and 129SV). In addition, Lamp2-deficient mice were smaller than wildtype mice. Surviving mice were fertile and had an almost normal life span. Ultrastructurally, there was extensive accumulation of autophagic vacuoles in many tissues, including liver, pancreas, spleen, kidney, and skeletal and heart muscle. In hepatocytes, the autophagic degradation of long-lived proteins was severely impaired. Cardiac myocytes were ultrastructurally abnormal and heart contractility was severely reduced. These findings indicated that LAMP2 is critical for autophagy. This theory was further substantiated by the finding that human LAMP2 deficiency, which causes Danon disease, is associated with the accumulation of autophagic material in striated myocytes. </p>

<p>In affected males from 3 different families with Danon disease (300257), Nishino et al. (2000) identified a 6-bp insertion at the junctions of exons 5 and 6 of the LAMP2 gene. The inserted nucleotides had the same sequence as the 5-prime end of intron 5. Conceivably, nucleotides 7 and 8 (GT) immediately after the inserted sequence in intron 5 were recognized as an alternative splice donor site. The inserted sequence encoded an in-frame stop codon, which predicted premature termination of the nascent polypeptide. This mutation was found in a Japanese family (patient 6), an African American family (patient 7), and an Anglo-Saxon family (patient 8). The African American family was originally reported by Danon et al. (1981), and the Anglo-Saxon family had been reported by Riggs et al. (1983). </p>

The proband was a 7-year-old boy with normal early motor and cognitive development, found to have an abnormal EKG and elevated blood creatinine kinase. EKG indicated left ventricular hypertrophy, confirmed by echocardiogram. Neurologic examination showed normal mentation and mild weakness of the neck muscles. He attended regular school.

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
component of our efforts to ensure long-term funding to provide you the
information that you need at your fingertips.
