Genes affected

TBC1D15 (HGNC:25694): (TBC1 domain family member 15) This gene encodes a member of the Ras-like proteins in brain-GTPase activating protein superfamily that share a conserved Tre-2/Bub2/Cdc16 domain. The encoded protein interacts with Ras-like protein in brain 5A and may function as a regulator of intracellular trafficking. Alternate splicing results in multiple transcript variants.

The c.1285G>A (p.D429N) alteration is located in exon 12 (coding exon 12) of the TBC1D15 gene. This alteration results from a G to A substitution at nucleotide position 1285, causing the aspartic acid (D) at amino acid position 429 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
