Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 06, 2021The c.636C>A (p.S212R) alteration is located in exon 6 (coding exon 6) of the RPP40 gene. This alteration results from a C to A substitution at nucleotide position 636, causing the serine (S) at amino acid position 212 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
