Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2022The c.513C>A (p.S171R) alteration is located in exon 3 (coding exon 1) of the RFPL4B gene. This alteration results from a C to A substitution at nucleotide position 513, causing the serine (S) at amino acid position 171 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
