Genes affected
TULP2 (HGNC:12424): (TUB like protein 2) TULP2 is a member of a family of tubby-like genes (TULPs) that encode proteins of unknown function. Members of this family have been identified in plants, vertebrates, and invertebrates. The TULP proteins share a conserved C-terminal region of approximately 200 amino acid residues.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 19, 2022The c.1039G>A (p.D347N) alteration is located in exon 9 (coding exon 8) of the TULP2 gene. This alteration results from a G to A substitution at nucleotide position 1039, causing the aspartic acid (D) at amino acid position 347 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
