Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Sep 07, 2022 | The c.811C>A (p.Q271K) alteration is located in exon 5 (coding exon 5) of the EEFSEC gene. This alteration results from a C to A substitution at nucleotide position 811, causing the glutamine (Q) at amino acid position 271 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
