Genes affected

DNAH17 (HGNC:2946): (dynein axonemal heavy chain 17) Dyneins are microtubule-associated motor protein complexes composed of several heavy, light, and intermediate chains. DNAH17 is a heavy chain associated with axonemal dynein (Milisav and Affara, 1998 [PubMed 9545504]).[supplied by OMIM, Mar 2008]

DNAH17 links:

PGS1 (HGNC:30029): (phosphatidylglycerophosphate synthase 1) Predicted to enable CDP-diacylglycerol-glycerol-3-phosphate 3-phosphatidyltransferase activity and calcium ion binding activity. Predicted to be involved in cardiolipin biosynthetic process and diacylglycerol metabolic process. Located in endoplasmic reticulum. [provided by Alliance of Genome Resources, Apr 2022]

The c.13346C>A (p.A4449E) alteration is located in exon 81 (coding exon 80) of the DNAH17 gene. This alteration results from a C to A substitution at nucleotide position 13346, causing the alanine (A) at amino acid position 4449 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
