Genes affected

ANKRD28 (HGNC:29024): (ankyrin repeat domain 28) Predicted to be located in cytosol and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ANKRD28 links:

BTD (HGNC:1122): (biotinidase) The protein encoded by this gene functions to recycle protein-bound biotin by cleaving biocytin (biotin-epsilon-lysine), a normal product of carboxylase degradation, resulting in regeneration of free biotin. The encoded protein has also been shown to have biotinyl transferase activity. Mutations in this gene are associated with biotinidase deficiency. Multiple transcript variants encoding different isoforms have been described. [provided by RefSeq, Aug 2013]

The c.2357G>A (p.G786E) alteration is located in exon 22 (coding exon 22) of the ANKRD28 gene. This alteration results from a G to A substitution at nucleotide position 2357, causing the glycine (G) at amino acid position 786 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
