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]

Mar 06, 2023

The c.262G>A (p.V88I) alteration is located in exon 2 (coding exon 2) of the TENM3 gene. This alteration results from a G to A substitution at nucleotide position 262, causing the valine (V) at amino acid position 88 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
