Genes affected

NHLRC3 (HGNC:33751): (NHL repeat containing 3) This gene encodes a protein containing NCL-1, HT2A and Lin-41 (NHL) family repeats. Mammalian NHL-repeat containing proteins may be involved in a variety of enzymatic processes, including protein modification through ubiquitination. Alternatively spliced transcript variants have been observed for this gene. [provided by RefSeq, Aug 2012]

Collection Method: clinical testing

The c.43C>T (p.L15F) alteration is located in exon 1 (coding exon 1) of the NHLRC3 gene. This alteration results from a C to T substitution at nucleotide position 43, causing the leucine (L) at amino acid position 15 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
