Genes affected

PIH1D1 (HGNC:26075): (PIH1 domain containing 1) Enables several functions, including RNA polymerase I core promoter sequence-specific DNA binding activity; enzyme binding activity; and phosphoprotein binding activity. Involved in several processes, including box C/D snoRNP assembly; positive regulation of signal transduction; and regulation of cellular protein metabolic process. Located in cytoplasm and nucleolus. Part of R2TP complex and pre-snoRNP complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.530A>G (p.Q177R) alteration is located in exon 6 (coding exon 6) of the PIH1D1 gene. This alteration results from a A to G substitution at nucleotide position 530, causing the glutamine (Q) at amino acid position 177 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
