Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM2 PP3_Moderate

The NM_014600.3(EHD3):​c.1169T>C​(p.Ile390Thr) variant causes a missense change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★).

• Frequency: Genomes: not found (cov: 32)
• Consequence: EHD3 NM_014600.3 missense
• Clinical Significance: Uncertain significance criteria provided, single submitter U:1
• Conservation: PhyloP100: 8.02

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.1169T>C (p.I390T) alteration is located in exon 6 (coding exon 6) of the EHD3 gene. This alteration results from a T to C substitution at nucleotide position 1169, causing the isoleucine (I) at amino acid position 390 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
