Position:

• chr5-146340088-GGCTCGCTGAGCCAA-G

Variant summary

Our verdict is Pathogenic. Variant got 11 ACMG points: 11P and 0B. PVS1 PM2 PP5

The NM_002700.3(POU4F3):​c.662_675del​(p.Gly221GlufsTer77) variant causes a frameshift change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. Variant has been reported in ClinVar as Pathogenic (no stars). Synonymous variant affecting the same amino acid position (i.e. G221G) has been classified as Benign.

• Frequency: Genomes: not found (cov: 33)
• Consequence: POU4F3 NM_002700.3 frameshift

Genes affected

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]

LOC127814297 (HGNC:):

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most exon, not predicted to undergo nonsense mediated mRNA decay. There are 29 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 5-146340088-GGCTCGCTGAGCCAA-G is Pathogenic according to our data. Variant chr5-146340088-GGCTCGCTGAGCCAA-G is described in ClinVar as [Pathogenic]. Clinvar id is 101525.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr5-146340088-GGCTCGCTGAGCCAA-G is described in Lovd as [Pathogenic].
