Collection Method: clinical testing

The c.68G>C (p.W23S) alteration is located in exon 1 (coding exon 1) of the EFCAB11 gene. This alteration results from a G to C substitution at nucleotide position 68, causing the tryptophan (W) at amino acid position 23 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
