Genes affected

LOC127814297 (HGNC:):

POU4F3 (HGNC:9220): (POU class 4 homeobox 3) This gene encodes a member of the POU-domain family of transcription factors. POU-domain proteins have been observed to play important roles in control of cell identity in several systems. This protein is found in the retina and may play a role in determining or maintaining the identities of a small subset of visual system neurons. Defects in this gene are the cause of non-syndromic sensorineural deafness autosomal dominant type 15. [provided by RefSeq, Mar 2009]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.08811784).
• BP6: Variant 5-146339190-T-A is Benign according to our data. Variant chr5-146339190-T-A is described in ClinVar as [Likely_benign]. Clinvar id is 2841950.Status of the report is criteria_provided_single_submitter, 1 stars.
