Genes affected

SFN (HGNC:10773): (stratifin) This gene encodes a cell cycle checkpoint protein. The encoded protein binds to translation and initiation factors and functions as a regulator of mitotic translation. In response to DNA damage this protein plays a role in preventing DNA errors during mitosis. [provided by RefSeq, Aug 2017]

Collection Method: clinical testing

The c.536T>A (p.F179Y) alteration is located in exon 1 (coding exon 1) of the SFN gene. This alteration results from a T to A substitution at nucleotide position 536, causing the phenylalanine (F) at amino acid position 179 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
