Genes affected

TENM3 (HGNC:29944): (teneurin transmembrane protein 3) This gene encodes a member of the teneurin transmembrane protein family. The encoded protein may be involved in the regulation of neuronal development including development of the visual pathway. Mutations in this gene have been associated with microphthalmia and developmental dysplasia of the hip. [provided by RefSeq, Jan 2023]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

PP2

Missense variant in gene, where missense usually causes diseases (based on misZ statistic), TENM3. . Gene score misZ 3.2996 (greater than the threshold 3.09). Trascript score misZ 3.8249 (greater than threshold 3.09). GenCC has associacion of gene with microphthalmia, isolated, with coloboma, microphthalmia, isolated, with coloboma 9.

BP4

Computational evidence support a benign effect (MetaRNN=0.021104902).

BS1

Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.0000526 (8/152182) while in subpopulation EAS AF= 0.00155 (8/5162). AF 95% confidence interval is 0.000771. There are 0 homozygotes in gnomad4. There are 5 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting

The c.90T>G (p.N30K) alteration is located in exon 1 (coding exon 1) of the TENM3 gene. This alteration results from a T to G substitution at nucleotide position 90, causing the asparagine (N) at amino acid position 30 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
