Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.83G>A (p.R28Q) alteration is located in exon 1 (coding exon 1) of the C2orf54 gene. This alteration results from a G to A substitution at nucleotide position 83, causing the arginine (R) at amino acid position 28 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
