Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 4P and 6B. PS3BP4_ModerateBS2

The NM_015141.4(GPD1L):c.839C>T(p.Ala280Val) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000837 in 1,613,366 control chromosomes in the GnomAD database, including 1 homozygotes. In-silico tool predicts a benign outcome for this variant. 16/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). ClinVar reports functional evidence for this variant: "SCV001360881: Multiple publications report experimental evidence evaluating an impact on protein function and demonstrated that the A280V variant caused lower enzyme activity, and resulted in decreased surface expression of SCN5A with lower Na currents (London_2007, Valdivia_2009).". Another variant affecting the same amino acid position, but resulting in a different missense (i.e. A280T) has been classified as Likely benign.

Genes affected

GPD1L (HGNC:28956): (glycerol-3-phosphate dehydrogenase 1 like) The protein encoded by this gene catalyzes the conversion of sn-glycerol 3-phosphate to glycerone phosphate. The encoded protein is found in the cytoplasm, associated with the plasma membrane, where it binds the sodium channel, voltage-gated, type V, alpha subunit (SCN5A). Defects in this gene are a cause of Brugada syndrome type 2 (BRS2) as well as sudden infant death syndrome (SIDS). [provided by RefSeq, Jul 2010]

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -2 ACMG points.

PS3

PS3 evidence extracted from ClinVar submissions: SCV001360881: Multiple publications report experimental evidence evaluating an impact on protein function and demonstrated that the A280V variant caused lower enzyme activity, and resulted in decreased surface expression of SCN5A with lower Na currents (London_2007, Valdivia_2009).

BP4

Computational evidence support a benign effect (MetaRNN=0.17950329).

BS2

High AC in GnomAd4 at 18 AD,Unknown gene.
