Genes affected
SLC35G5 (HGNC:15546): (solute carrier family 35 member G5) This gene is intronless and probably arose from retrotransposition of a similar gene. It has high sequence similarity to the gene encoding acyl-malonyl condensing enzyme on chromosome 17. [provided by RefSeq, Aug 2011]
MTMR9 (HGNC:14596): (myotubularin related protein 9) This gene encodes a myotubularin-related protein that is atypical to most other members of the myotubularin-related protein family because it has no dual-specificity phosphatase domain. The encoded protein contains a double-helical motif similar to the SET interaction domain, which is thought to have a role in the control of cell proliferation. In mouse, a protein similar to the encoded protein binds with MTMR7, and together they dephosphorylate phosphatidylinositol 3-phosphate and inositol 1,3-bisphosphate. [provided by RefSeq, Jul 2008]

The c.55C>A (p.P19T) alteration is located in exon 1 (coding exon 1) of the SLC35G5 gene. This alteration results from a C to A substitution at nucleotide position 55, causing the proline (P) at amino acid position 19 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
