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]

Submissions by phenotype
not specified Uncertain:1
Uncertain significance, criteria provided, single submitter | clinical testing | Ambry Genetics | Apr 07, 2023 | The c.433A>T (p.I145F) 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 433, causing the isoleucine (I) at amino acid position 145 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. - |
