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 GeneticsDec 15, 2023The c.1117C>T (p.R373W) alteration is located in exon 10 (coding exon 9) of the TULP2 gene. This alteration results from a C to T substitution at nucleotide position 1117, causing the arginine (R) at amino acid position 373 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
