Genetic Variant SPTBN5:p.Arg3602His (chr15-41851089-C-T) – ACMG Classification: Likely_benign (-6 pts)

Variant summary

Our verdict is Likely benign. The variant received -6 ACMG points: 0P and 6B. BP4_StrongBP6_Moderate

The NM_016642.4(SPTBN5):c.10805G>A(p.Arg3602His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000769 in 1,612,830 control chromosomes in the GnomAD database, including 2 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R3602L) has been classified as Uncertain significance.

Genes affected

SPTBN5 (HGNC:15680): (spectrin beta, non-erythrocytic 5) Enables several functions, including cytoskeletal protein binding activity; dynein intermediate chain binding activity; and identical protein binding activity. Acts upstream of or within Golgi organization and lysosomal transport. Located in cytoplasm; photoreceptor connecting cilium; and photoreceptor disc membrane.
