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]

The c.881G>T (p.C294F) alteration is located in exon 4 (coding exon 4) of the WNT7A gene. This alteration results from a G to T substitution at nucleotide position 881, causing the cysteine (C) at amino acid position 294 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
