Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 02, 2021The c.3427C>T (p.R1143C) alteration is located in exon 22 (coding exon 21) of the RPAP1 gene. This alteration results from a C to T substitution at nucleotide position 3427, causing the arginine (R) at amino acid position 1143 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
