Low match METHYLMALONIC ACIDURIA AND HOMOCYSTINURIA, CBLC TYPE; MAHCC

Combined methylmalonic aciduria (MMA) and homocystinuria is a genetically heterogeneous disorder of cobalamin (cbl; vitamin B12) metabolism. The defect causes decreased levels of the coenzymes adenosylcobalamin (AdoCbl) and methylcobalamin (MeCbl), which results in decreased activity of the respective enzymes methylmalonyl-CoA mutase (MUT ) and methyltetrahydrofolate:homocysteine methyltransferase, also known as methionine synthase (MTR ). Different forms of the disorder have been classified according to complementation groups of cells in vitro: cblC, cblD (OMIM ), cblF (OMIM ), and cblJ (OMIM ).Isolated methylmalonic acidurias have also been classified by complementation groups: MMA 'mut' (OMIM ) is caused by mutation in the MUT gene on chromosome 6p21; MMA cblA (OMIM ) is caused by mutation in the MMAA gene (OMIM ) on 4q31; and MMA cblB (OMIM ) is caused by mutation in the MMAB gene (OMIM ) on 12q24.Methylmalonic aciduria and homocystinuria, cblC type, is the most common inborn error of vitamin B12 (cobalamin) metabolism, with about 250 known cases (Lerner-Ellis et al., 2006). Affected individuals may have developmental, hematologic, neurologic, metabolic, ophthalmologic, and dermatologic clinical findings. Although considered a disease of infancy or childhood, some individuals develop symptoms in adulthood (Rosenblatt et al., 1997).

Low match NEURODEGENERATION WITH BRAIN IRON ACCUMULATION 1; NBIA1

Neurodegeneration with brain iron accumulation is a genetically heterogeneous disorder characterized by progressive iron accumulation in the basal ganglia and other regions of the brain, resulting in extrapyramidal movements, such as parkinsonism and dystonia. Age at onset, severity, and cognitive involvement are variable (review by Gregory et al., 2009).Panthothenate kinase-associated neurodegeneration has been classified clinically as 'classic,' 'atypical,' or 'intermediate.' In the classic form, patients present within the first decade of life with rapidly progressing disease and loss of ambulation approximately 15 years later. In the atypical form, patients have onset in the second decade with slow progression and maintain independent ambulation after 15 years. In the intermediate form, patients have early onset and slow progression or later onset and rapid progression. Patients with early onset tend to develop pigmentary retinopathy, whereas those with later onset tend to have speech disorders and psychiatric features. All patients have the 'eye of the tiger' sign on brain MRI (Hayflick et al., 2003; Pellecchia et al., 2005).Kumar et al. (2006) noted that the 'eye of the tiger' sign is not pathognomonic for PANK2 mutations. They reported 2 unrelated adult patients with cognitive dysfunction who had the characteristic sign on MRI but did not have mutations in the PANK2 gene.Gregory et al. (2009) provided a detailed review of the different forms of neurodegeneration with brain iron accumulation.In addition, some patients with Kufor-Rakeb syndrome (OMIM ), also known as Parkinson disease-9 (PARK9), have iron deposition in the basal ganglia. Genetic Heterogeneity of Neurodegeneration with Brain Iron AccumulationNeurodegeneration with brain iron accumulation is an umbrella term that encompasses a group of genetically heterogeneous disorders. See also NBIA2A (OMIM ) and NBIA2B (OMIM ), both caused by mutation in the PLA2G6 gene (OMIM ); NBIA3 (OMIM ), caused by mutation in the FTL gene (OMIM ); NBIA4 (OMIM ), caused by mutation in the C19ORF12 gene (OMIM ); NBIA5 (OMIM ), caused by mutation in the WDR45 gene (OMIM ); NBIA6 (OMIM ), caused by mutation in the COASY gene (OMIM ); NBIA7 (OMIM ), caused by mutation in the REPS1 gene (OMIM ); and NBIA8 (OMIM ), caused by mutation in the CRAT gene (OMIM ).See review of Schneider and Bhatia (2012) on syndromes of neurodegeneration with brain iron accumulation, including Kufor-Rakeb disease (OMIM ) and aceruloplasminemia (OMIM ).

Achondroplasia is the most frequent form of short-limb dwarfism. Affected individuals exhibit short stature caused by rhizomelic shortening of the limbs, characteristic facies with frontal bossing and midface hypoplasia, exaggerated lumbar lordosis, limitation of elbow extension, genu varum, and trident hand (summary by Bellus et al., 1995).

Low match BLOOD GROUP, SS; SS

Ss blood group antigens reside on the red-cell glycoprotein GYPB. The S and s antigens result from a polymorphism at amino acid 29 of GYPB, where S has met29 and s has thr29. The U antigen refers to a short extracellular sequence in GYPB located near the membrane. GYPB, glycophorin A (GYPA ), and glycophorin E (GYPE ) are closely linked on chromosome 4q31. Antigens of the MN blood group (OMIM ) reside on GYPA. The M and N antigens differ at amino acids 1 and 5 of GYPA, where M is ser-ser-thr-thr-gly, and N is leu-ser-thr-thr-glu. The N terminus of GYPB is essentially identical to that of GYPA except that it always expresses the N antigen, denoted 'N' or N-prime. Recombination and gene conversion between GYPA, GYPB, and GYPE lead to hybrid glycophorin molecules and generation of low-incidence antigens. Thus, the MN and Ss blood groups are together referred to as the MNSs blood group system (see {111300}). Recombination results in 3 glycophorin-null phenotypes: En(a-) cells lack GYPA due to recombination between GYPA and GYPB; GYPB-negative (S-s-U-) cells lack GYPB due to recombination in GYPB; and M(k) cells (M-N-S-s-U-) lack both GYPA and GYPB due to recombination between GYPA and GYPE. Individuals with glycophorin-null phenotypes have decreased sialic acid content and increased resistance to malarial infection (see {611162}). GYPA and GYPB are not essential for red-cell development or survival, and GYPA- and GYPB-null phenotypes are not associated with anemia or altered red-cell function (review by Cooling, 2015).
