Collection Method: clinical testing

The c.277C>A (p.Q93K) alteration is located in exon 4 (coding exon 4) of the SPIC gene. This alteration results from a C to A substitution at nucleotide position 277, causing the glutamine (Q) at amino acid position 93 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
