Genes affected
NECTIN3 (HGNC:17664): (nectin cell adhesion molecule 3) This gene encodes a member of the nectin family of proteins, which function as adhesion molecules at adherens junctions. This family member interacts with other nectin-like proteins and with afadin, a filamentous actin-binding protein involved in the regulation of directional motility, cell proliferation and survival. This gene plays a role in ocular development involving the ciliary body. Mutations in this gene are believed to result in congenital ocular defects. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2011]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 11, 2021The c.702T>A (p.F234L) alteration is located in exon 1 (coding exon 1) of the NECTIN3 gene. This alteration results from a T to A substitution at nucleotide position 702, causing the phenylalanine (F) at amino acid position 234 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
