Genes affected

AFG1L (HGNC:16411): (AFG1 like ATPase) This gene encodes a mitochondrial integral membrane protein that plays a role in mitochondrial protein homeostasis. The protein contains a P-loop motif and a five-domain structure that is conserved in fly, yeast, and bacteria. It functions to mediate the degradation of nuclear-encoded complex IV subunits. Two conserved estrogen receptor binding sites are located within 2.5 kb of this gene. Polymorphisms in this gene have been associated with bipolar disorder. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2016]

The c.815G>T (p.C272F) alteration is located in exon 8 (coding exon 8) of the LACE1 gene. This alteration results from a G to T substitution at nucleotide position 815, causing the cysteine (C) at amino acid position 272 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
