Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.287T>C (p.F96S) alteration is located in exon 6 (coding exon 4) of the SUPT3H gene. This alteration results from a T to C substitution at nucleotide position 287, causing the phenylalanine (F) at amino acid position 96 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
