• rs2242374
• NM_152599.4:c.1323C>A

Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 2P and 5B. PM2 BP4_Strong BP7

The NM_152599.4(MFSD6L):​c.1323C>A​(p.Leu441Leu) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. L441L) has been classified as Benign.

• Frequency: Genomes: not found (cov: 32)
• Consequence: MFSD6L NM_152599.4 synonymous
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -2.95

Genes affected

MFSD6L (HGNC:26656): (major facilitator superfamily domain containing 6 like) Predicted to be integral component of membrane. Predicted to be active in membrane. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.8).
• BP7: Synonymous conserved (PhyloP=-2.95 with no splicing effect.
