- Fanconi anemia complementation group P [DOID:0111092]
A Fanconi anemia characterized by increased chromosomal instability, progressive bone marrow failure and in some cases skeletal abnormalities that has_material_basis_in homozygous or compound heterozygous mutation in the SLX4 gene on chromosome 16p13.3.
- Lown-Ganong-Levine syndrome [DOID:13087]
A syndrome that involves pre-excitation of the ventricles due to an accessory pathway providing an abnormal electrical communication from the atria to the ventricles.
- second-degree atrioventricular block [DOID:0050822]
An atrioventricular block that is characterized by progressive prolongation of the PR interval on consecutive beats followed by a blocked P wave on electrocardiogram or intermittently non-conducted P waves not preceded by PR changes on electrocardiogram caused by a conduction block between the atria and the ventricles through the atrioventricular node.
- chromosome 16p12.1 deletion syndrome [DOID:0060399]
A chromosomal deletion syndrome that has_material_basis_in a 520 kb deletion on the short (p) arm of the chromosome at a location designated 16p12.1 and is characterized by developmental delay, craniofacial dysmorphology, and congenital heart defects.
- third-degree atrioventricular block [DOID:0050823]
An atrioventricular block that is characterized by bradycardia, hypotension, hemodynamic instability and complete dissociation between P waves and QRS complexes on electrocardiogram caused when conduction fails to propagate from atria to ventricles.
- Cri-Du-Chat syndrome [DOID:12580]
A syndrome that has_material_basis_in deletion of the end of the chromosome 5 p arm and that is characterized by intellectual disability, delayed development, small head size, low birth weight, weak muscle tone widely set eyes, low-set ears, a small jaw, a rounded face and a high-pitched cry that sounds like that of a cat.
- congenital disorder of glycosylation Ig [DOID:0080559]
A congenital disorder of glycosylation I that is characterized by facial dysmorphism (prominent forehead, large ears, thin upper lip), generalized hypotonia, feeding difficulties, moderate to severe developmental delay, progressive microcephaly, frequent upper respiratory tract infections due to impaired immunity with decreased immunoglobulin levels, and decreased coagulation factors and has_material_basis_in homozygous or compound heterozygous mutation in the gene encoding dolichyl-P-mannose:Man-7-GlcNAc-2-PP-dolichyl-alpha-6-mannosyltransferase on chromosome 22q13.
