Genes affected

POU3F4 (HGNC:9217): (POU class 3 homeobox 4) This gene encodes a member of the POU-III class of neural transcription factors. This family member plays a role in inner ear development. The protein is thought to be involved in the mediation of epigenetic signals which induce striatal neuron-precursor differentiation. Mutations in this gene are associated with X chromosome-linked nonsyndromic mixed deafness. [provided by RefSeq, Dec 2012]

The POU3F4 p.Pro47Ser variant was not identified in the literature nor was it identified in LOVD 3.0. The variant was identified in dbSNP (ID: rs144417952) and ClinVar (classified as likely benign by Laboratory for Molecular Medicine and Illumina). The variant was also identified in control databases in 97 of 198285 chromosomes (26 hemizygous) at a frequency of 0.000489 (Genome Aggregation Database Feb 27, 2017). The variant was observed in the following populations: African in 76 of 18537 chromosomes (freq: 0.0041), Latino in 7 of 27514 chromosomes (freq: 0.000254) and European (non-Finnish) in 14 of 88908 chromosomes (freq: 0.000158), but was not observed in the Ashkenazi Jewish, East Asian, European (Finnish), Other or South Asian populations. The p.Pro47 residue is conserved in mammals and computational analyses (PolyPhen-2, SIFT, AlignGVGD, BLOSUM, MutationTaster) provide inconsistent predictions regarding the impact to the protein; this information is not very predictive of pathogenicity. The variant occurs outside of the splicing consensus sequence and in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a difference in splicing. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -

Significance: Benign

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
