DNA/RNA

 
Description 5 exons, spans approximately 160 kb; a sixth alternative terminal exon within intron 3 has been described
Transcription RNA: 4.1 kb. Transcription initiated from two different promoter regions. A polymorphic dinucleotide repeat upstream of the ATG start codon strongly regulates HMGA2 expression. Moreover, HMGA2 is controlled by negatively acting regulatory elements within the 3'UTR

Protein

 
Description 109 amino acids; three DNA binding domains (AT hooks) linked to the carboxy-terminal acidic domain that does not activate transcription
Expression fetal tissues: expression in various tissues, prominent in kidney, liver and uterus; adult tissues: no expression except in lung and kidney; tumors: expression in benign mesenchymal tumor tissues correlated to 12q15 rearrangements; expressed in malignant tumours (e.g., in breast tumours, pancreas tumours, lung tumours, nerve system tumours, oral cavity tumours).
Localisation nuclear
Function architectural factor, non histone, preferential binding to AT rich sequences in the minor groove of DNA helix; the precise function remains to be elucidated; probable role in regulation of cell proliferation
Homology member of the HMGI protein family

Mutations

Germinal deletion of HMGIC in mutant mice or transgenic ' knock out' mice for the first two exons of HMGIC have the "pigmy" phenotype: low birth weight, craniofacial defects, adipocyte hypoplasia adult body weight about 40% of normal; mice with a partial or complete deficiency of HMGA2 resisted diet-induced obesity implicating a role of the gene in fat cell proliferation; truncations of mouse Hmga2 in transgenic mice result in somatic overgrowth and, in particular, increased abundance of fat and lipomas; overexpression of the HMGA2 gene in transgenic mice leads to the onset of pituary adenomas secreting prolactic and growth hormone; HMGA2-null mice had very few spermatids and complete absence of spermatozoa;
8-year-old boy had a de novo pericentric inversion of chromosome 12, with breakpoints at p11.22 and q14.3. The phenotype included extreme somatic overgrowth, advanced endochondral bone and dental ages, a cerebellar tumour, and multiple lipomas. His chromosomal inversion was found to truncate HMGA2, which maps to the 12q14.3 breakpoint;

Implicated in

Entity MESENCHYMAL BENIGN TUMORS as follows:
  
Entity Lipoma
Disease benign adipocyte tumor
Prognosis good
Cytogenetics various rearrangements involving 12q15 (translocations, inversions, deletions...); reciprocal translocations involve 12q15 with different partners such as chromosomes 1, 2, 3, 7, 10, 11, 13, 15, 17, 21, X; the most frequent anomaly is t(3;12)(q27-28;q15); cryptic rearrangements, such as paracentric inversions not detectable by conventional cytogenetics but detectable by FISH, have been described
Hybrid/Mutated Gene for t(3;12): HMGIC-LPP (LPP: lipoma preferred partner; 3q27-28); a gene located in 13q, LHFP (lipoma HMGIC fusion partner) was found to be fused with HMGIC in one case of lipoma; one lipoma displayed fusion of HMGA2 exon 4 with a sequence from intron 4, indicating abnormal splicing; HMGA2-CMKOR1 in three cases with aberrations involving 2q35-37 and 12q13-15; HMGA2-NFIB in one lipoma;
Abnormal Protein HMGIC-LPP; the three AT hook domains at the aminoterminal of HMGIC are fused to the LIM domain of LPP; another fusion protein due to the fusion of HMGIC with a putative gene located at 15q24 predicted to encode a protein with a serine/threonine-rich domain has also been described
Oncogenesis the relevance of the exact role LPP in the HMGA2-LPP fusion is not established yet, but the transactivation functions of the LPP LIM domains is retained in the fusion protein and the fusion protein can function as a transcription factor; the truncation of HMGA2 by itself may have a role in the tumorigenesis
  
Entity Uterine leiomyoma (uterine fibroids)
Disease benign mesenchymal tumors
Prognosis good
Cytogenetics approximately 40% of uterine leiomyomas have structural chromosomal rearrangements, about 10% of which involve 12q15 (translocations, inversions, deletions...); the most frequent anomaly is t(12;14)(q15;q23-24)
 
Hybrid/Mutated Gene in a majority of cases, there is no fusion gene: the breakpoint is located 10 kb up to 100 kb 5' to HMGIC; the recombinational repair gene RAD51B is a candidate to be the partner gene of HMGIC in t(12;14). In two cases (out of 81 primary tumors) exon 7 of RAD51B was fused in frame to either exon 2 or 3 of the HMGA2 gene; in one case with paracentric inversion, HMGIC exon 3 was fused to ALDH2 exon 13 (12q24.1); in one case (no cytogenetic analysis) HMGIC exon 3 was fused to COX6C 3' UTR (8q22-23); in one case, with apparently normal karyotype, exon 3 of HMGIC was fused to retrotransposon-like sequences RTVLH 3' LTRs; three fusion transcripts contained 3' cryptic exonic sequences present in intron 3 of the HMGA2 gene (breakpoints downstream of exons 3 or 4), suggesting that they are due to alternative splicing; one case displayed fusion of the first two exons of HMGA2 to the 3' portion of the CCNB1IP1/C14orf18/HEI10 gene
Abnormal Protein HMGIC-ALDH2: ALDH2 contribution was only 10 amino acids;
Oncogenesis HMGIC-ALDH2: it is suggested that the truncation of HMGIC, rather than fusion may be responsible for tumorigenesis; the 3' untranslated region may stabilize the HMGIC messenger RNA
  
Entity Pleomorphic adenoma of the salivary gland (or mixed salivary gland tumor)
Disease benign tumors from the major or minor salivary glands
Prognosis good
Cytogenetics approximately 12% of pleomorphic adenomas of salivary glands show abnormalities involving HMGIC in 12q15; the most frequent aberration is t(9;12)(p24.1;q15)
Hybrid/Mutated Gene in t(9;12): HMGIC-NFIB fusion; another type of fusion HMGIC-FHIT (3p14.2) has also been described
  
Entity Pulmonary chondroid hamartoma of the lung
Disease benign mesenchymal tumors of the lung
Prognosis good
Cytogenetics various rearrangements involving 12q15 leading to HMGIC dysregulation; cryptic rearrangements such as paracentric inversions not detectable by conventional cytogenetics but detectable by FISH have been described
Hybrid/Mutated Gene in two cases with apparently normal karyotypes, exon 3 of HMGIC was fused to retrotransposon-like sequences RTVLH 3' LTRs; in cases with t(3;12)(q27-28;q14-15) (see lipomas), a fusion of HMGA2-LPP was described; only 1/61 cases with normal karyotype displayed HMGA2-LPP fusion; three cases with rearrangements involving 12q14-15 and 13q12-14 lacked rearrangements of HMGA2-LHFP;
 
  
Entity Endometrial polyps
Disease uterine benign tumors
Prognosis good

Prognosis variable
Cytogenetics one case with t(4;12)(q32;q15) and one case with t(5;12)(p14;q15)
