The c.1001G>T (p.R334L) alteration is located in exon 6 (coding exon 5) of the OSGEPL1 gene. This alteration results from a G to T substitution at nucleotide position 1001, causing the arginine (R) at amino acid position 334 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
