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.

Ambry Genetics

Sep 15, 2021

The c.784C>T (p.R262C) alteration is located in exon 8 (coding exon 7) of the TULP2 gene. This alteration results from a C to T substitution at nucleotide position 784, causing the arginine (R) at amino acid position 262 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
