Genes affected

FGF8 (HGNC:3686): (fibroblast growth factor 8) The protein encoded by this gene is a member of the fibroblast growth factor (FGF) family. FGF family members possess broad mitogenic and cell survival activities, and are involved in a variety of biological processes, including embryonic development, cell growth, morphogenesis, tissue repair, tumor growth and invasion. This protein is known to be a factor that supports androgen and anchorage independent growth of mammary tumor cells. Overexpression of this gene has been shown to increase tumor growth and angiogensis. The adult expression of this gene is restricted to testes and ovaries. Temporal and spatial pattern of this gene expression suggests its function as an embryonic epithelial factor. Studies of the mouse and chick homologs revealed roles in midbrain and limb development, organogenesis, embryo gastrulation and left-right axis determination. The alternative splicing of this gene results in four transcript variants. [provided by RefSeq, Jul 2008]

LOC105378457 (HGNC:):

ACMG classification

Verdict is Benign. Variant got -8 ACMG points.

• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.0322 (3888/120620) while in subpopulation NFE AF= 0.0415 (2428/58498). AF 95% confidence interval is 0.0401. There are 74 homozygotes in gnomad4. There are 1707 alleles in male gnomad4 subpopulation. Median coverage is 0. This position pass quality control queck.
• BS2: High AC in GnomAd4 at 3888 AD,Digenic gene.
