Pulmonary fibrosis and/or bone marrow failure syndrome, telomere-related, 8(PFBMFT8)

MedGen UID:

Concept ID:
C5830496

Synonym: PFBMFT8

OMIM®: 620367

Definition

Telomere-related pulmonary fibrosis and/or bone marrow failure syndrome-8 (PFBMFT8) is an autosomal dominant disorder characterized by the onset of progressive pulmonary fibrosis in adulthood. Some affected individuals have signs of bone marrow failure, such as thrombocytopenia, or liver dysfunction, including hepatopulmonary syndrome. Other features of dyskeratosis congenita, including premature graying of the hair, may be observed. Telomeres are shortened compared to controls (Kelich et al., 2022). For a discussion of genetic heterogeneity of telomere-related pulmonary fibrosis and/or bone marrow failure, see PFBMFT1 (614742). [from OMIM]

Disease or Syndrome
Diffuse benign transformation of the hepatic parenchyma into small regenerative nodules with minimal or no fibrosis.
Thrombocytopenia
MedGen UID:
52737
Concept ID:
C0040034
Disease or Syndrome
A reduction in the number of circulating thrombocytes.
Increased mean corpuscular volume
MedGen UID:
81303
Concept ID:
C0302845
Finding
Larger than normal size of erythrocytes.
Dyspnea
MedGen UID:
3938
Concept ID:
C0013404
Sign or Symptom
Difficult or labored breathing. Dyspnea is a subjective feeling only the patient can rate, e.g., on a Borg scale.
Pulmonary fibrosis
MedGen UID:
11028
Concept ID:
C0034069
Disease or Syndrome
Replacement of normal lung tissues by fibroblasts and collagen.
Inspiratory crackles
MedGen UID:
661427
Concept ID:
C0577961
Finding
Crackles that are heard during the inspiratory phase.
Nonproductive cough
MedGen UID:
163087
Concept ID:
C0850149
Sign or Symptom
A cough that does not produce phlegm or mucus.
Decreased DLCO
MedGen UID:
892993
Concept ID:
C4073175
Finding
Reduced ability of the lungs to transfer gas from inspired air to the bloodstream as measured by the diffusing capacity of the lungs for carbon monoxide (DLCO) test.
Usual interstitial pneumonia
MedGen UID:
1662563
Concept ID:
C4721509
Disease or Syndrome
Temporal and spatial heterogeneity in lungs based on presence of fibrosis and honeycombing.
Splenomegaly
MedGen UID:
52469
Concept ID:
C0038002
Finding
Abnormal increased size of the spleen.
Premature graying of hair
MedGen UID:
75524
Concept ID:
C0263498
Finding
Development of gray hair at a younger than normal age.
Short telomere length
MedGen UID:
1627435
Concept ID:
C4531138
Anatomical Abnormality
An abnormal reduction in telomere length. Telomeres are non-coding, repetitive sequences of DNA at the ends of the chromosomes of eukaryotic cells which become shorter as cells divide, and when telomere attrition reaches its limit, cell proliferation arrest, senescence, and apoptosis can occur.
