Genes affected
DRC3 (HGNC:25384): (dynein regulatory complex subunit 3) Located in axoneme. [provided by Alliance of Genome Resources, Apr 2022]
ATPAF2 (HGNC:18802): (ATP synthase mitochondrial F1 complex assembly factor 2) This gene encodes an assembly factor for the F(1) component of the mitochondrial ATP synthase. This protein binds specifically to the F1 alpha subunit and is thought to prevent this subunit from forming nonproductive homooligomers during enzyme assembly. This gene is located within the Smith-Magenis syndrome region on chromosome 17. An alternatively spliced transcript variant has been described, but its biological validity has not been determined.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 14, 2023The c.161A>G (p.N54S) alteration is located in exon 5 (coding exon 2) of the DRC3 gene. This alteration results from a A to G substitution at nucleotide position 161, causing the asparagine (N) at amino acid position 54 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
