Genes affected
FRMD7 (HGNC:8079): (FERM domain containing 7) Predicted to enable guanyl-nucleotide exchange factor activity. Predicted to be involved in regulation of neuron projection development. Predicted to act upstream of or within several processes, including negative regulation of stress fiber assembly; positive regulation of lamellipodium assembly; and positive regulation of small GTPase mediated signal transduction. Located in cytosol; nucleoplasm; and plasma membrane. Implicated in congenital nystagmus 1. [provided by Alliance of Genome Resources, Apr 2022]

Benign, criteria provided, single submitterclinical testingIllumina Laboratory Services, IlluminaJan 13, 2018This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
