The c.624C>A (p.S208R) alteration is located in exon 1 (coding exon 1) of the HDGFL1 gene. This alteration results from a C to A substitution at nucleotide position 624, causing the serine (S) at amino acid position 208 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
