Collection Method: clinical testing

The c.710C>T (p.T237M) alteration is located in exon 7 (coding exon 7) of the SCAF8 gene. This alteration results from a C to T substitution at nucleotide position 710, causing the threonine (T) at amino acid position 237 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
