Osteopetrosis, autosomal recessive 9(OPTB9)

MedGen UID:
1841123
Concept ID:
C5830487
Disease or Syndrome
Synonyms: OPTB9; OSTEOPETROSIS, IKEGAWA TYPE
 
Gene (location): SLC4A2 (7q36.1)
 
Monarch Initiative: MONDO:0957262
OMIM®: 620366

Definition

Autosomal recessive osteopetrosis-9 (OPTB9) is characterized by increased bone density and bone fragility, as well as renal failure. Vision may be compromised due to compression of the optic nerve secondary to osteopetrotic stenosis of the optic nerve canal (Xue et al., 2022). For a general phenotypic description and discussion of genetic heterogeneity of autosomal recessive osteopetrosis, see OPTB1 (259700). [from OMIM]

Clinical features

From HPO
Stage 3 chronic kidney disease
MedGen UID:
389222
Concept ID:
C2316787
Disease or Syndrome
A type of chronic kidney disease with moderately reduced glomerular filtration rate (GFR 30-59 mL/min/1.73 m2).
Postnatal growth retardation
MedGen UID:
395343
Concept ID:
C1859778
Finding
Slow or limited growth after birth.
Anemia
MedGen UID:
1526
Concept ID:
C0002871
Disease or Syndrome
A reduction in erythrocytes volume or hemoglobin concentration.
Pathologic fracture
MedGen UID:
42095
Concept ID:
C0016663
Pathologic Function
A pathologic fracture occurs when a bone breaks in an area that is weakened secondarily to another disease process such as tumor, infection, and certain inherited bone disorders. A pathologic fracture can occur without a degree of trauma required to cause fracture in healthy bone.
Osteopetrosis
MedGen UID:
18223
Concept ID:
C0029454
Finding
Abnormally increased formation of dense trabecular bone tissue. Despite the increased density of bone tissue, osteopetrotic bones tend to be more fracture-prone than normal.
Increased bone mineral density
MedGen UID:
10502
Concept ID:
C0029464
Disease or Syndrome
An abnormal increase of bone mineral density, that is, of the amount of matter per cubic centimeter of bones which is often referred to as osteosclerosis. Osteosclerosis can be detected on radiological examination as an increased whiteness (density) of affected bones.
Thick skull base
MedGen UID:
326511
Concept ID:
C1839507
Finding
Cortical sclerosis
MedGen UID:
870710
Concept ID:
C4025164
Pathologic Function
Sclerosis (abnormal hardening) of cortical bone, characterized by increased radiodensity.
Hyperkalemia
MedGen UID:
5691
Concept ID:
C0020461
Finding
An abnormally increased potassium concentration in the blood.
Elevated circulating creatinine concentration
MedGen UID:
148579
Concept ID:
C0700225
Finding
An increased amount of creatinine in the blood.
Elevated circulating alkaline phosphatase concentration
MedGen UID:
727252
Concept ID:
C1314665
Finding
Abnormally increased serum levels of alkaline phosphatase activity.
Hyperparathyroidism
MedGen UID:
6967
Concept ID:
C0020502
Disease or Syndrome
Excessive production of parathyroid hormone (PTH) by the parathyroid glands.
Optic papillitis
MedGen UID:
10565
Concept ID:
C0030353
Finding
Papilledema refers to edema (swelling) of the optic disc secondary to any factor which increases cerebral spinal fluid pressure.
Reduced visual acuity
MedGen UID:
65889
Concept ID:
C0234632
Finding
Diminished clarity of vision.
