Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.559G>A (p.E187K) alteration is located in exon 3 (coding exon 3) of the ZNF551 gene. This alteration results from a G to A substitution at nucleotide position 559, causing the glutamic acid (E) at amino acid position 187 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
