Collection Method: clinical testing

The c.596C>T (p.S199L) alteration is located in exon 6 (coding exon 5) of the GGNBP2 gene. This alteration results from a C to T substitution at nucleotide position 596, causing the serine (S) at amino acid position 199 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
