Genes affected
TBC1D32 (HGNC:21485): (TBC1 domain family member 32) This gene encodes a TBC-domain containing protein. Studies of a similar protein in mouse and zebrafish suggest that the encoded protein is involved in sonic hedgehog signaling, and that it interacts with and stabilizes cell cycle-related kinase. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 10, 2023The c.3576C>G (p.I1192M) alteration is located in exon 31 (coding exon 31) of the TBC1D32 gene. This alteration results from a C to G substitution at nucleotide position 3576, causing the isoleucine (I) at amino acid position 1192 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
