Variant summary

Our verdict is Benign. Variant got -14 ACMG points: 0P and 14B. BP4_Strong BP6_Moderate BA1

The NM_003879.7(CFLAR):c.607C>A(p.Leu203Ile) variant causes a missense, splice region change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00392 in 1,597,212 control chromosomes in the GnomAD database, including 223 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/22 in silico tools predict a benign outcome for this variant. 3/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Benign (★). Another nucleotide change resulting in same amino acid change has been previously reported as Likely benignin UniProt.

Genes affected

CFLAR (HGNC:1876): (CASP8 and FADD like apoptosis regulator) The protein encoded by this gene is a regulator of apoptosis and is structurally similar to caspase-8. However, the encoded protein lacks caspase activity and appears to be itself cleaved into two peptides by caspase-8. Several transcript variants encoding different isoforms have been found for this gene, and partial evidence for several more variants exists. [provided by RefSeq, Feb 2011]

CFLAR-AS1 (HGNC:14437): (CFLAR antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0014910996).
• BP6: Variant 2-201145378-C-A is Benign according to our data. Variant chr2-201145378-C-A is described in ClinVar as [Benign]. Clinvar id is 783347.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.0685 is higher than 0.05.
