Genes affected

RNF32 (HGNC:17118): (ring finger protein 32) The protein encoded by this gene contains two RING ring finger motifs. RING finger motifs are present in a variety of functionally distinct proteins and are known to be involved in protein-DNA or protein-protein interactions. This gene was found to be expressed during spermatogenesis, most likely in spermatocytes and/or in spermatids. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Apr 2015]

RNF32 links:

LMBR1 (HGNC:13243): (limb development membrane protein 1) This gene encodes a member of the LMBR1-like membrane protein family. Another member of this protein family has been shown to be a lipocalin transmembrane receptor. A highly conserved, cis-acting regulatory module for the sonic hedgehog gene is located within an intron of this gene. Consequently, disruption of this genic region can alter sonic hedgehog expression and affect limb patterning, but it is not known if this gene functions directly in limb development. Mutations and chromosomal deletions and rearrangements in this genic region are associated with acheiropody and preaxial polydactyly, which likely result from altered sonic hedgehog expression.

The c.1015G>A (p.V339M) alteration is located in exon 9 (coding exon 8) of the RNF32 gene. This alteration results from a G to A substitution at nucleotide position 1015, causing the valine (V) at amino acid position 339 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
