The c.2077C>T (p.L693F) alteration is located in exon 10 (coding exon 9) of the NDST4 gene. This alteration results from a C to T substitution at nucleotide position 2077, causing the leucine (L) at amino acid position 693 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
