The c.3208C>T (p.H1070Y) alteration is located in exon 19 (coding exon 18) of the IGSF9 gene. This alteration results from a C to T substitution at nucleotide position 3208, causing the histidine (H) at amino acid position 1070 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
