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

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

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 Fuhrmann syndrome, phocomelia, Schinzel type.
BP4
Computational evidence support a benign effect (MetaRNN=0.30881757).
BS1
Variant frequency is greater than expected in population amr. GnomAd4 allele frequency = 0.0000526 (8/152178) while in subpopulation AMR AF = 0.000458 (7/15280). AF 95% confidence interval is 0.000215. There are 0 homozygotes in GnomAd4. There are 6 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.919A>T (p.M307L) alteration is located in exon 4 (coding exon 4) of the WNT7A gene. This alteration results from a A to T substitution at nucleotide position 919, causing the methionine (M) at amino acid position 307 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
