Collection Method: clinical testing

The c.1861A>T (p.I621L) alteration is located in exon 8 (coding exon 8) of the GOLGA6L6 gene. This alteration results from a A to T substitution at nucleotide position 1861, causing the isoleucine (I) at amino acid position 621 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
