The CACNA1D p.Phe1923del variant was not identified in the literature nor was it identified in LOVD 3.0. The variant was identified in dbSNP (ID: rs72556363) and ClinVar (classified as likely benign by Center for Pediatric Genomic Medicine, Children's Mercy Hospital and Clinics and as benign by Laboratory for Molecular Medicine, Partners HealthCare Personalized Medicine). The variant was identified in control databases in 673 of 278936 chromosomes (3 homozygous) at a frequency of 0.002413 increasing the likelihood this could be a low frequency benign variant (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: European (non-Finnish) in 588 of 129052 chromosomes (freq: 0.004556), Other in 15 of 7200 chromosomes (freq: 0.002083), European (Finnish) in 20 of 21356 chromosomes (freq: 0.000937), African in 21 of 24966 chromosomes (freq: 0.000841), Latino in 24 of 35436 chromosomes (freq: 0.000677), Ashkenazi Jewish in 2 of 10368 chromosomes (freq: 0.000193) and South Asian in 3 of 30616 chromosomes (freq: 0.000098), but was not observed in the East Asian population. This variant is an in-frame deletion resulting in the removal of a phenylalanine (phe) residue at codon 1923; the impact of this alteration on CACNA1D protein function is not known. The variant occurs outside of the splicing consensus sequence and three of four in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) do not predict a greater than 10% difference in splicing; this is not very predictive of pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time although we would lean towards a more benign role for this variant. This variant is classified as likely benign. -
