Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 22, 2021The c.666A>C (p.R222S) alteration is located in exon 8 (coding exon 8) of the C22orf42 gene. This alteration results from a A to C substitution at nucleotide position 666, causing the arginine (R) at amino acid position 222 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
