Mendeliome v1.850 PMEPA1 Zornitza Stark Phenotypes for gene: PMEPA1 were changed from Familial thoracic aortic aneurysm disease (FTAAD); Loeys-Dietz syndrome to Hereditary disorder of connective tissue, MONDO:0023603, PMEPA1-related
Mendeliome v1.849 PMEPA1 Zornitza Stark reviewed gene: PMEPA1: Rating: AMBER; Mode of pathogenicity: None; Publications: ; Phenotypes: Hereditary disorder of connective tissue, MONDO:0023603, PMEPA1-related; Mode of inheritance: MONOALLELIC, autosomal or pseudoautosomal, NOT imprinted
Mendeliome v1.847 PMEPA1 Hazel Phillimore changed review comment from: PMID: 36928819; Greene, D. et al. (2023) Nat Med. 29(3):679-688.

Eight families with truncating variants affecting the same stretch of cytosines in this gene.

In the 100KGP discovery cohort, in three families with Familial thoracic aortic aneurysm disease (FTAAD) of European ancestry, the variant found was an insertion of a cytosine within a seven-cytosine stretch in the last exon, predicted to cause p.(S209Qfs*3). This variant was also identified independently in eight affected members of three pedigrees of Japanese ancestry in a separate Japanese patient group.
Also, this study found a deletion of one of those cytosines causing p.(S209Afs*61), in one individual or family.
Also, there was one family in Belgium in which the affected members carried a 5-bp deletion in the same stretch of polycytosines inducing a frameshift p.(P207Qfs*3).

Phenotypic analysis of the individuals suggest that the phenotype of these FTAAD individuals and families is more like Loeys-Dietz syndrome.

(Note: the variant is present in gnomAD v2.1.1 in 22 heterozygotes as a filtered out variant.).

Also, this study found a deletion of one of those cytosines causing p.(S209Afs*61), in one individual or family.
Also, there was one family in Belgium in which the affected members carried a 5-bp deletion in the same stretch of polycytosines inducing a frameshift p.(P207Qfs*3).
