Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 26, 2021The c.188G>C (p.R63P) alteration is located in exon 1 (coding exon 1) of the C2orf54 gene. This alteration results from a G to C substitution at nucleotide position 188, causing the arginine (R) at amino acid position 63 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
