Collection Method: clinical testing

The c.329C>A (p.P110Q) alteration is located in exon 4 (coding exon 4) of the EFCAB5 gene. This alteration results from a C to A substitution at nucleotide position 329, causing the proline (P) at amino acid position 110 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
