• NM_006236.3:c.98G>C

Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 1P and 4B. PP2 BP4_Strong

The NM_006236.3(POU3F3):​c.98G>C​(p.Gly33Ala) variant causes a missense change involving the alteration of a non-conserved nucleotide. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G33E) has been classified as Uncertain significance.

Genes affected

POU3F3 (HGNC:9216): (POU class 3 homeobox 3) This gene encodes a POU-domain containing protein that functions as a transcription factor. The encoded protein recognizes an octamer sequence in the DNA of target genes. This protein may play a role in development of the nervous system. [provided by RefSeq, Apr 2015]

ENSG00000269707 (HGNC:):

PANTR1 (HGNC:49513): (POU3F3 adjacent non-coding transcript 1) Predicted to act upstream of or within regulation of gene expression. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PP2: Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 12 curated pathogenic missense variants (we use a threshold of 10). The gene has 2 curated benign missense variants. Gene score misZ: 3.0416 (below the threshold of 3.09). Trascript score misZ: -0.11043 (below the threshold of 3.09). GenCC associations: The gene is linked to snijders blok-fisher syndrome.
• BP4: Computational evidence support a benign effect (MetaRNN=0.049422532).
