Genes affected

EHD3 (HGNC:3244): (EH domain containing 3) Predicted to enable nucleic acid binding activity. Involved in several processes, including Golgi to lysosome transport; endosomal transport; and protein homooligomerization. Acts upstream of or within protein localization to plasma membrane and regulation of cardiac muscle cell membrane potential. Located in ciliary pocket membrane and recycling endosome membrane.

The c.869C>T (p.A290V) alteration is located in exon 4 (coding exon 4) of the EHD3 gene. This alteration results from a C to T substitution at nucleotide position 869, causing the alanine (A) at amino acid position 290 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
