Genes affected
PRR12 (HGNC:29217): (proline rich 12) This gene encodes a proline-rich protein that contains two A-T hook DNA binding domains. A chromosomal translocation and gene fusion between this gene and zinc finger, MIZ-type containing 1 (Gene ID: 57178) may underlie intellectual disability and neuropsychiatric problems in a human patient. Enriched expression of this gene in embryonic mouse brain suggests that this gene may play a role in nervous system development. [provided by RefSeq, Jul 2016]

Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 29, 2020The alteration results in an amino acid change:_x000D_ _x000D_ The c.236C>A (p.A79E) alteration is located in coding exon 3 of the PRR12 gene. This alteration results from a C to A substitution at nucleotide position 236, causing the alanine (A) at amino acid position 79 to be replaced by a glutamic acid (E). The alteration is not observed in population databases: _x000D_ _x000D_ Based on data from the Genome Aggregation Database (gnomAD), the PRR12 c.236C>A alteration was not observed, with coverage at this position. The altered amino acid is not conserved throughout evolution:_x000D_ _x000D_ The p.A79 amino acid is not conserved in available vertebrate species. The alteration is predicted tolerated by in silico modeling:_x000D_ _x000D_ The p.A79E alteration is predicted to be tolerated by in silico analysis. Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
