Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 09, 2021The c.376C>A (p.R126S) alteration is located in exon 4 (coding exon 1) of the C21orf62 gene. This alteration results from a C to A substitution at nucleotide position 376, causing the arginine (R) at amino acid position 126 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
