Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 08, 2024The c.1564G>A (p.G522S) alteration is located in exon 1 (coding exon 1) of the CECR6 gene. This alteration results from a G to A substitution at nucleotide position 1564, causing the glycine (G) at amino acid position 522 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
