Genes affected
HACL1 (HGNC:17856): (2-hydroxyacyl-CoA lyase 1) Enables several functions, including 2-hydroxy-3-methylhexadecanoyl-CoA lyase activity; ATP binding activity; and cation binding activity. Involved in fatty acid alpha-oxidation; phytanic acid metabolic process; and protein targeting to peroxisome. Located in nucleoplasm and peroxisome. [provided by Alliance of Genome Resources, Apr 2022]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.15C>G (p.N5K) alteration is located in exon 1 (coding exon 1) of the HACL1 gene. This alteration results from a C to G substitution at nucleotide position 15, causing the asparagine (N) at amino acid position 5 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
