Genes affected

ADAP1 (HGNC:16486): (ArfGAP with dual PH domains 1) Enables GTPase activator activity. Involved in regulation of GTPase activity. Located in cytosol; nucleus; and plasma membrane. [provided by Alliance of Genome Resources, Apr 2022]

ADAP1 links:

COX19 (HGNC:28074): (cytochrome c oxidase assembly factor COX19) COX19 encodes a cytochrome c oxidase (COX)-assembly protein. The S. cerevisiae Cox19 protein may play a role in metal transport to the mitochondrial intermembrane space and assembly of complex IV of the mitochondrial respiratory chain (Sacconi et al., 2005 [PubMed 16212937]).[supplied by OMIM, Mar 2008]

Ambry Genetics

Jan 04, 2022

The c.242C>T (p.A81V) alteration is located in exon 3 (coding exon 3) of the ADAP1 gene. This alteration results from a C to T substitution at nucleotide position 242, causing the alanine (A) at amino acid position 81 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
