Genes affected

C4orf46 (HGNC:27320): (chromosome 4 open reading frame 46) This gene encodes a small, conserved protein of unknown function that is expressed in a variety of tissues. There are pseudogenes for this gene on chromosomes 6, 8, 16, and X. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Feb 2013]

Ambry Genetics

Nov 09, 2021

The c.211C>A (p.L71I) alteration is located in exon 2 (coding exon 2) of the C4orf46 gene. This alteration results from a C to A substitution at nucleotide position 211, causing the leucine (L) at amino acid position 71 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
