Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.83C>T (p.S28L) alteration is located in exon 1 (coding exon 1) of the GTSF1L gene. This alteration results from a C to T substitution at nucleotide position 83, causing the serine (S) at amino acid position 28 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
