Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The c.4G>C (p.E2Q) alteration is located in exon 1 (coding exon 1) of the ANKFN1 gene. This alteration results from a G to C substitution at nucleotide position 4, causing the glutamic acid (E) at amino acid position 2 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
