Variant summary

Our verdict is Benign. The variant received -11 ACMG points: 2P and 13B. PM1BP4_StrongBP6BS1BS2

The NM_006261.5(PROP1):c.52G>A(p.Gly18Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000131 in 1,614,072 control chromosomes in the GnomAD database, including 5 homozygotes. In-silico tool predicts a benign outcome for this variant. 17/22 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G18C) has been classified as Uncertain significance.

Genes affected

PROP1 (HGNC:9455): (PROP paired-like homeobox 1) This gene encodes a paired-like homeodomain transcription factor in the developing pituitary gland. Expression occurs prior to and is required for expression of pou domain transcription factor 1, which is responsible for pituitary development and hormone expression. Mutations in this gene have been associated with combined pituitary hormone deficiency-2 as well as deficiencies in luteinizing hormone, follicle-stimulating hormone, growth hormone, prolactin, and thyroid-stimulating hormone.

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -11 ACMG points.

PM1

In a chain Homeobox protein prophet of Pit-1 (size 225) in uniprot entity PROP1_HUMAN there are 38 pathogenic changes around while only 8 benign (83%) in NM_006261.5

BP4

Computational evidence support a benign effect (MetaRNN=0.007876307).

BP6

Variant 5-177995882-C-T is Benign according to our data. Variant chr5-177995882-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 288237.

BS1

Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000105 (16/152330) while in subpopulation SAS AF = 0.00228 (11/4828). AF 95% confidence interval is 0.00128. There are 0 homozygotes in GnomAd4. There are 14 alleles in the male GnomAd4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 5 AR,AD gene
