Atrial septal dilatation

MedGen UID:
1384602
Concept ID:
C4476553
Anatomical Abnormality
Synonym: Atrial septal aneurysm
 
HPO: HP:0011995
Monarch Initiative: MONDO:0020438
Orphanet: ORPHA99107

Definition

A bulging of the interatrial septum towards one side. In adults, atrial septal aneurysm can be defined as a protrusion of the aneurysm of >10 mm beyond the plane of the atrial septum as measured by transesophageal echocardiography. [from HPO]

Conditions with this feature

Holt-Oram syndrome
MedGen UID:
120524
Concept ID:
C0265264
Disease or Syndrome
Holt-Oram syndrome (HOS) is characterized by upper-limb defects, congenital heart malformation, and cardiac conduction disease. Upper-limb malformations may be unilateral, bilateral/symmetric, or bilateral/asymmetric and can range from triphalangeal or absent thumb(s) to phocomelia. Other upper-limb malformations can include unequal arm length caused by aplasia or hypoplasia of the radius, fusion or anomalous development of the carpal and thenar bones, abnormal forearm pronation and supination, abnormal opposition of the thumb, sloping shoulders, and restriction of shoulder joint movement. An abnormal carpal bone is present in all affected individuals and may be the only evidence of disease. A congenital heart malformation is present in 75% of individuals with HOS and most commonly involves the septum. Atrial septal defect and ventricular septal defect can vary in number, size, and location. Complex congenital heart malformations can also occur in individuals with HOS. Individuals with HOS with or without a congenital heart malformation are at risk for cardiac conduction disease. While individuals may present at birth with sinus bradycardia and first-degree atrioventricular (AV) block, AV block can progress unpredictably to a higher grade including complete heart block with and without atrial fibrillation.
Wrinkly skin syndrome
MedGen UID:
98030
Concept ID:
C0406587
Disease or Syndrome
ATP6V0A2-related cutis laxa is characterized by generalized cutis laxa, findings associated with generalized connective tissue disorder, developmental delays, and a variety of neurologic findings including abnormality on brain MRI. At birth, hypotonia, overfolded skin, and distinctive facial features are present and enlarged fontanelles are often observed. During childhood, the characteristic facial features and thick or coarse hair may become quite pronounced. The skin findings decrease with age, although easy bruising and Ehlers-Danlos-like scars have been described in some. In most (not all) affected individuals, cortical and cerebellar malformations are observed on brain MRI. Nearly all affected individuals have developmental delays, seizures, and neurologic regression.
Atrial septal defect 1
MedGen UID:

C1862389
Congenital Abnormality
Secundum atrial septal defect (ASD) is a common congenital heart malformation that occurs as an isolated anomaly in 10% of individuals with congenital heart disease. Uncorrected ASD can cause pulmonary overcirculation, right heart volume overload, and premature death (summary by Benson et al., 1998). Genetic Heterogeneity of Atrial Septal Defect The ASD1 locus has been mapped to chromosome 5p. Other forms of atrial septal defect that are associated with other congenital heart disease but no conduction defects or noncardiac abnormalities include ASD2 (607941), caused by mutation in the GATA4 gene (600576), and ASD4 (611363), caused by mutation in the TBX20 gene (606061). ASD3 (614089) and ASD5 (612794), in which atrial septal defect is not associated with other cardiac abnormalities, are caused by mutation in the MYH6 (160710) and ACTC1 (102540) genes, respectively. ASD6 (613087), in which atrial septal defect may be associated with aneurysm of the interatrial septum and cardiac arrhythmias, is caused by mutation in the TLL1 gene (606742). ASD7 (108900), in which ASD is often associated with atrioventricular conduction defects, is caused by mutation in the NKX2-5 gene (600584). ASD8 (614433), in which ASD may be associated with other cardiac anomalies, is caused by mutation in the CITED2 gene (602937). ASD9 (614475) is caused by mutation in the GATA6 gene (601656). Somatic mutations in the HAND1 gene (602406) have been identified in tissue samples from patients with ASDs.
