Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 17, 2021The c.1047G>C (p.Q349H) alteration is located in exon 4 (coding exon 4) of the C2orf54 gene. This alteration results from a G to C substitution at nucleotide position 1047, causing the glutamine (Q) at amino acid position 349 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
