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)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2022The c.659A>T (p.Q220L) alteration is located in exon 6 (coding exon 5) of the CFLAR gene. This alteration results from a A to T substitution at nucleotide position 659, causing the glutamine (Q) at amino acid position 220 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
