Genes affected

WNT7A (HGNC:12786): (Wnt family member 7A) This gene is a member of the WNT gene family, which consists of structurally related genes that encode secreted signaling proteins. These proteins have been implicated in oncogenesis and in several developmental processes, including regulation of cell fate and patterning during embryogenesis. This gene is involved in the development of the anterior-posterior axis in the female reproductive tract, and also plays a critical role in uterine smooth muscle pattering and maintenance of adult uterine function. Mutations in this gene are associated with Fuhrmann and Al-Awadi/Raas-Rothschild/Schinzel phocomelia syndromes. [provided by RefSeq, Jul 2008]

ACMG classification

Our verdict: Pathogenic. The variant received 15 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 6 curated pathogenic missense variants (we use a threshold of 10). The gene has 1 curated benign missense variants. Gene score misZ: 1.3439 (below the threshold of 3.09). Trascript score misZ: 1.655 (below the threshold of 3.09). GenCC associations: The gene is linked to phocomelia, Schinzel type, Fuhrmann syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.994
• PP5: Variant 3-13819384-C-T is Pathogenic according to our data. Variant chr3-13819384-C-T is described in ClinVar as Pathogenic/Likely_pathogenic. ClinVar VariationId is 35537.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
