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.443A>T (p.E148V) alteration is located in exon 5 (coding exon 5) of the PIH1D1 gene. This alteration results from a A to T substitution at nucleotide position 443, causing the glutamic acid (E) at amino acid position 148 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
