Genes affected

FOXS1 (HGNC:3735): (forkhead box S1) The forkhead family of transcription factors belongs to the winged helix class of DNA-binding proteins. The protein encoded by this intronless gene contains a forkhead domain and is found predominantly in aorta and kidney. The function of the encoded protein is unknown. [provided by RefSeq, Jul 2008]

Collection Method:clinical testing

The c.554G>T (p.R185M) alteration is located in exon 1 (coding exon 1) of the FOXS1 gene. This alteration results from a G to T substitution at nucleotide position 554, causing the arginine (R) at amino acid position 185 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
