Genes affected

RPP21 (HGNC:21300): (ribonuclease P/MRP subunit p21) RPP21 is a protein subunit of nuclear ribonuclease P, which processes the 5-prime leader sequence of precursor tRNAs (Jarrous et al., 2001 [PubMed 11497433]).[supplied by OMIM, Jan 2009]

The c.173C>T (p.S58F) alteration is located in exon 3 (coding exon 3) of the RPP21 gene. This alteration results from a C to T substitution at nucleotide position 173, causing the serine (S) at amino acid position 58 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
