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.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2023The c.974G>C (p.R325T) alteration is located in exon 9 (coding exon 8) of the TULP2 gene. This alteration results from a G to C substitution at nucleotide position 974, causing the arginine (R) at amino acid position 325 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
