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).
Autosomal recessive inheritance (Orphanet)
 
Gene (location): ERCC6L2 (9q22.32)

Definition

Bone marrow failure syndrome-2 is an autosomal recessive disorder characterized by trilineage bone marrow failure, learning disabilities, and microcephaly. Cutaneous features and increased chromosome breakage are not features (Tummala et al., 2014). For a discussion of genetic heterogeneity of BMFS, see BMFS1 (614675). [from OMIM]

Leukopenia
MedGen UID:
6073
•Concept ID:
C0023530
•
Disease or Syndrome
An abnormal decreased number of leukocytes in the blood.

Cutaneous photosensitivity
MedGen UID:
87601
•Concept ID:
C0349506
•
Pathologic Function
An increased sensitivity of the skin to light. Photosensitivity may result in a rash upon exposure to the sun (which is known as photodermatosis). Photosensitivity can be diagnosed by phototests in which light is shone on small areas of skin.
