The c.4828A>T (p.S1610C) alteration is located in exon 7 (coding exon 7) of the NHSL1 gene. This alteration results from a A to T substitution at nucleotide position 4828, causing the serine (S) at amino acid position 1610 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
