Autosomal recessive inheritance
MedGen UID:

Concept ID:
C0441748
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).
 
Gene (location): PAPSS2 (10q23.2-23.31)

Definition

This form of brachyolmia, here designated brachyolmia type 4, is characterized by short-trunk stature with normal intelligence and facies. The radiographic features include rectangular vertebral bodies with irregular endplates and narrow intervertebral discs, precocious calcification of rib cartilages, short femoral neck, mildly shortened metacarpals, and mild epiphyseal and metaphyseal changes of the tubular bones (summary by Miyake et al., 2012). [from OMIM]

Clinical features

From HPO
Secondary amenorrhea
MedGen UID:
115919
Concept ID:
C0232940
Disease or Syndrome
The cessation of menstruation for six months or more in a female that is not pregnant, breastfeeding or menopausal.
Brachydactyly
MedGen UID:
67454
Concept ID:
C0221357
Congenital Abnormality
Digits that appear disproportionately short compared to the hand/foot. The word brachydactyly is used here to describe a series distinct patterns of shortened digits (brachydactyly types A-E). This is the sense used here.
Lower limb undergrowth
MedGen UID:
138016
Concept ID:
C0345371
Congenital Abnormality
Leg shortening because of underdevelopment of one or more bones of the lower extremity.
Short stature
MedGen UID:
87607
Concept ID:
C0349588
Finding
A height below that which is expected according to age and gender norms. Although there is no universally accepted definition of short stature, many refer to "short stature" as height more than 2 standard deviations below the mean for age and gender (or below the 3rd percentile for age and gender dependent norms).
Spondyloepimetaphyseal dysplasia
MedGen UID:
609408
Concept ID:
C0432211
Disease or Syndrome
An osteochondrodysplasia that results in abnormalities of bone growth in the vertebral column, epiphysis, and metaphysis.
Kyphoscoliosis
MedGen UID:
154361
Concept ID:
C0575158
Anatomical Abnormality
An abnormal curvature of the spine in both a coronal (lateral) and sagittal (back-to-front) plane.
Irregular vertebral endplates
MedGen UID:
331233
Concept ID:
C1842153
Finding
An irregular surface of the vertebral end plates, which are normally relatively smooth.
Platyspondyly
MedGen UID:
335010
Concept ID:
C1844704
Finding
A flattened vertebral body shape with reduced distance between the vertebral endplates.
Lumbar scoliosis
MedGen UID:
412568

152379
Concept ID:
C0702166
Disease or Syndrome
A skin condition in which there is an increase in sebum secretion by the pilosebaceous apparatus associated with open comedones (blackheads), closed comedones (whiteheads), and pustular nodules (papules, pustules, and cysts).
Hirsutism
MedGen UID:
42461
Concept ID:
C0019572
Disease or Syndrome
Abnormally increased hair growth referring to a male pattern of body hair (androgenic hair).
