Collection Method: clinical testing

The c.944G>T (p.G315V) alteration is located in exon 8 (coding exon 8) of the LIPM gene. This alteration results from a G to T substitution at nucleotide position 944, causing the glycine (G) at amino acid position 315 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
