Variant summary
Our verdict is Likely benign. The variant received -4 ACMG points: 1P and 5B. PP3BP6BS2
The NM_001376.5(DYNC1H1):c.13771C>T(p.Arg4591Cys) variant causes a missense change. The variant allele was found at a frequency of 0.0000112 in 1,614,064 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R4591H) has been classified as Likely benign.

Inborn genetic diseases Uncertain:1
The p.R4591C variant (also known as c.13771C>T), located in coding exon 77 of the DYNC1H1 gene, results from a C to T substitution at nucleotide position 13771. The arginine at codon 4591 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
