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 GeneticsMar 17, 2023The c.1129A>G (p.T377A) alteration is located in exon 10 (coding exon 9) of the TULP2 gene. This alteration results from a A to G substitution at nucleotide position 1129, causing the threonine (T) at amino acid position 377 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
